Question 251: The following statistical diagram is known as
- A. Kaplan Meier plot
- B. Spaghetti plot
- C. Funnel plot
- D. Forest plot (Correct Answer)
Explanation: ***Forest plot*** - This diagram, featuring a series of horizontal lines (representing **confidence intervals**) for different studies or outcomes, centered around a point estimate (often a **hazard ratio** or odds ratio), is characteristic of a forest plot. - Forest plots are commonly used in **meta-analyses** to graphically present the results of individual studies and their combined effect. *Kaplan Meier plot* - A Kaplan-Meier plot is a **survival curve** that shows the probability of a subject surviving beyond a certain time point. - It consists of a **stepwise function** decreasing over time, rather than individual point estimates with confidence intervals. *Spaghetti plot* - A spaghetti plot is used to display **multiple time series** on a single graph, where each line represents an individual's data over time. - This type of plot helps visualize **individual variability** and trends, but it does not represent hazard ratios or confidence intervals in the way shown. *Funnel plot* - A funnel plot is a scatter plot used to detect **publication bias** in meta-analyses, where the effect size is plotted against a measure of study precision. - It typically appears as a symmetrical, **funnel-shaped distribution** of points, which is visually distinct from the given diagram.
Question 252: The following symbol is used to depict awareness for which disease?
- A. Diabetes
- B. Breast cancer (Correct Answer)
- C. Cervical cancer
- D. Hypertension
Explanation: ***Breast cancer*** - The **pink ribbon** is an internationally recognised symbol for breast cancer awareness. - It is prominently used in campaigns, especially during **Breast Cancer Awareness Month** in October, to promote screening and early detection. *Diabetes* - The symbol for diabetes awareness is typically a **blue circle**, representing the global unity in the fight against diabetes. - While it's a significant health issue, it does not use the pink ribbon for its awareness campaigns. *Cervical cancer* - The awareness ribbon for cervical cancer is typically **teal and white**. - This symbol highlights the importance of vaccination and regular screening tests like Pap smears. *Hypertension* - There isn't a universally recognized ribbon symbol for hypertension; however, sometimes a **red dress** or variations of a **red ribbon** are used for heart health awareness in general. - Hypertension awareness focuses on lifestyle modifications, regular monitoring, and medication adherence.
Question 253: The logo of which national health programme is shown below? (Recent NEET Pattern 2016-17)
- A. RCH (Correct Answer)
- B. NRHM
- C. NPCDCS
- D. Navjaat Shishu Suraksha Karyakram
Explanation: ***Correct Option: RCH*** - The logo shown, with the tagline **"Health in Your Hands"** (and its Hindi equivalent), is the official logo for the **Reproductive and Child Health (RCH)** program in India. - This program focuses on improving the health of mothers, children, and adolescents through various interventions. *Incorrect Option: NRHM* - The **National Rural Health Mission (NRHM)** aims to provide accessible, affordable, and accountable healthcare, primarily to rural populations. - Its logo and thematic focus are broader than the family-centric imagery of the RCH logo, which specifically emphasizes reproductive and child health. *Incorrect Option: NPCDCS* - The **National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS)** focuses on non-communicable diseases. - Its objectives and visual branding are distinct from the RCH program, which targets maternal and child health. *Incorrect Option: Navjaat Shishu Suraksha Karyakram* - The **Navjaat Shishu Suraksha Karyakram** is a specific initiative under the broader RCH program, focusing on essential newborn care at birth. - While related, it is a component program, and its logo would be more specific to newborn care rather than the general "Health in Your Hands" message encompassing reproductive and child health.
Question 254: Identify the programme depicted by symbol as given in the image: (Recent NEET Pattern 2016-17)
- A. NPCB
- B. NVBDCP (Correct Answer)
- C. RCH
- D. ICDS
Explanation: **NVBDCP** - The image depicts a family with a child, surrounded by a protective arc, which is the official logo for the **National Vector Borne Disease Control Programme (NVBDCP)**. - This programme focuses on controlling vector-borne diseases that affect families and communities, reflecting the protective and public health aspect of the logo. *NPCB* - NPCB stands for the **National Programme for Control of Blindness and Visual Impairment**, which has a distinct logo focused on eyes or vision-related imagery. - The logo in the question does not contain any visual elements related to eyes or vision. *RCH* - RCH stands for **Reproductive and Child Health Programme**, which usually focuses on maternal and child health, often symbolized by a mother and child figure. - While it involves children, the common RCH logos generally emphasize the mother and child in a specific context of reproduction and maternal care, not a general family as shown. *ICDS* - ICDS stands for **Integrated Child Development Services**, aiming at holistic development of young children, pregnant women, and lactating mothers. - Its logo typically features imagery reflecting child development, nutrition, and early childhood care, which is different from the protective family symbol shown.
Question 255: Identify the programme symbol as given in the image:

NEET-PG 2017 - General Medicine NEET-PG Practice Questions and MCQs
Question 251: All are correct about the condition shown below except:
- A. Calcification of interosseous membrane (Correct Answer)
- B. Multiple lytic lesions in vertebra
- C. Barrel chest
- D. Bony exostosis in limb bones
Explanation: ***Calcification of interosseous membrane*** - The image shows features consistent with **fluorosis**, a condition caused by excessive fluoride intake. While fluorosis can lead to widespread calcification of ligaments and tendons, **calcification of the interosseous membrane** is a characteristic but often later finding. - The patient exhibits **genu valgum** (knock-knees) and the radiograph of the forearm shows diffuse increased bone density and osteosclerosis, typical of fluorosis. *Multiple lytic lesions in vertebra* - **Fluorosis** primarily causes **osteosclerosis** (increased bone density) and periosteal bone formation, not lytic lesions. - **Lytic lesions in vertebrae** are more often associated with conditions like multiple myeloma, metastatic cancer, or infections, which involve bone destruction rather than excessive bone formation. *Barrel chest* - **Barrel chest** is typically associated with chronic obstructive pulmonary disease (COPD) or other respiratory conditions that cause hyperinflation of the lungs. - While **skeletal deformities** are common in advanced fluorosis, a "barrel chest" is not a direct or characteristic manifestation of the condition. *Bony exostosis in limb bones* - **Bony exostoses** (osteochondromas) are generally seen in hereditary multiple exostoses or can be isolated benign bone tumors. - While fluorosis causes irregular new bone formation and thickening of long bones, specific, discrete **bony exostoses** are not a typical feature; rather, it's a more generalized osteosclerosis and periostitis.

Which of the following is correct about the media shown below?
The following diagram depicts blood smear of which species?
NEET-PG 2017 - Microbiology NEET-PG Practice Questions and MCQs
Question 251: The image shows:
- A. Alkaline peptone water
- B. Lowenstein Jensen media
- C. Cary Blair medium
- D. Robertson cooked meat broth (Correct Answer)
Explanation: ***Robertson cooked meat broth*** - The image displays a glass jar containing a **meat-based medium** at the bottom, covered with a liquid, which is characteristic of Robertson cooked meat broth. - This medium is primarily used for the **cultivation of anaerobic bacteria**, as the meat particles create an anaerobic environment and provide nutrients. *Alkaline peptone water* - Alkaline peptone water is a **liquid enrichment medium** that appears as a clear, yellowish broth without any particulate matter like cooked meat. - It is specifically used for the enrichment of *Vibrio cholerae* due to its high pH. *Lowenstein Jensen media* - Lowenstein Jensen media is a **solid egg-based medium** that is typically green in color and typically slants in test tubes or petri dishes. - It is used for the isolation and culture of **mycobacteria**, and its appearance is distinctly different from the image. *Cary Blair medium* - Cary Blair medium is a **semisolid transport medium** used for the preservation of enteric bacteria in stool samples. - It appears as a clear or slightly opalescent gel in a tube and does not contain visible chunks of meat.
Question 252: Which of the following is correct about the media shown below?
- A. Saccharolytic bacteria turn meat black
- B. Proteolytic bacteria turn meat red
- C. Liquid paraffin layering over the broth prevents air entry (Correct Answer)
- D. Favor growth of microaerophilic bacteria
Explanation: ***Liquid paraffin layering over the broth prevents air entry*** - The image depicts **Cooked Meat Medium (CMM)**, which is used primarily for cultivating **anaerobic bacteria**, particularly Clostridia species. - **Liquid paraffin layering** on top of the broth is a key feature of CMM that **creates anaerobic conditions** by preventing oxygen diffusion into the medium. - This technique, combined with the reducing substances from meat particles, ensures a truly anaerobic environment suitable for obligate anaerobes. *Saccharolytic bacteria turn meat black* - **Saccharolytic bacteria** primarily ferment carbohydrates and produce acid/gas, but do not typically cause blackening of meat. - Blackening in CMM is associated with **hydrogen sulfide (H2S) production** by proteolytic bacteria, not saccharolytic activity. *Proteolytic bacteria turn meat red* - This is incorrect. **Proteolytic bacteria** break down proteins and typically turn the meat particles **black** due to H2S production. - The digestion of meat proteins by proteolytic Clostridia results in darkening (blackening), not reddening of the medium. *Favor growth of microaerophilic bacteria* - CMM is designed for **anaerobic bacteria**, not microaerophiles. - **Microaerophilic bacteria** require low oxygen tension (5-10% O2) and are cultivated in specialized conditions like candle jars or microaerophilic atmosphere generators, not in CMM. - CMM provides an anaerobic environment through liquid paraffin seal and reducing agents from meat.
Question 253: The following diagram depicts blood smear of which species?
- A. Plasmodium malariae
- B. Plasmodium ovale
- C. Plasmodium falciparum (Correct Answer)
- D. Plasmodium vivax
Explanation: ***Plasmodium falciparum*** - The image displays characteristic **crescent-shaped or banana-shaped gametocytes** (stages 16-20), which are **pathognomonic for *Plasmodium falciparum*** - The earlier stages (1-5) represent ring forms (multiple rings per RBC, delicate ring forms) - Subsequent stages (6-15) show maturation culminating in the distinct **crescentic gametocytes** - This morphology is the **key distinguishing feature** of P. falciparum *Plasmodium vivax* - Produces **oval-shaped gametocytes**, not crescent-shaped - Characterized by enlarged RBCs with **Schüffner's dots** - Shows amoeboid trophozoites, not seen in this smear *Plasmodium malariae* - Produces **oval to round gametocytes** - Characteristic **band forms** and **rosette-shaped schizonts** (8-12 merozoites) - Not crescent-shaped as shown in the image *Plasmodium ovale* - Produces **oval gametocytes** similar to P. vivax - RBCs show **fimbriated edges** and Schüffner's dots - Does not produce crescent-shaped gametocytes
