Nursing Elites

1. Why is the specific gravity for infants lower than for older children?

• A. Infants have a greater body surface area.
• B. Infants have a higher basal metabolic rate.
• C. Infants have a greater percentage of body weight that is water.
• D. Infants' kidneys are less able to concentrate urine.

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

2. A nurse assesses a male patient who has developed gynecomastia while receiving treatment for peptic ulcers. Which medication from the patient�s history should the nurse recognize as a contributing factor?

• A. Amoxicillin (Amoxil)
• B. Cimetidine (Tagamet)
• C. Metronidazole (Flagyl)
• D. Omeprazole (Prilosec)

Correct answer: B

Rationale: Cimetidine binds to androgen receptors, producing receptor blockade, which can cause enlarged breast tissue, reduced libido, and impotence. All these effects reverse when dosing stops. Amoxicillin, metronidazole, and omeprazole are not associated with gynecomastia.

3. What is the corrected age of a child born at 30 weeks gestation on May 2, 2014, who is being tested on August 5, 2014?

• A. 3 months
• B. 2 weeks
• C. 2.6 months
• D. 4 weeks

Correct answer: B

Rationale: To calculate the corrected age of a premature child, you need to adjust for the weeks of prematurity. In this case, the child was born at 30 weeks gestation. From May 2, 2014, to August 5, 2014, is a span of 14 weeks. Subtracting the 30 weeks of gestation from the total time passed (14 weeks) gives the corrected age, which is 14 - 30 = -16 weeks. Since negative weeks are not relevant here, the corrected age is 0 weeks, which is equivalent to 2 weeks. Choice A is incorrect because 3 months is not the correct adjustment for the given scenario. Choice C is incorrect as it provides a fractional value for age, which is not practical in this context. Choice D is incorrect as 4 weeks does not account for the weeks of prematurity.

4. After administering Gardasil, the HPV vaccine, to an 11-year-old girl, the healthcare provider informs the parent that routine screening with which diagnostic test is needed?

• A. Beta hCG
• B. Chlamydia test
• C. PAP test
• D. Mammogram

Correct answer: C

Rationale: Following the administration of Gardasil, the HPV vaccine, routine screening with a PAP test is necessary. While Gardasil protects against certain types of HPV, it does not cover all strains that could lead to cervical cancer. Therefore, individuals who have received the vaccine should still undergo regular PAP tests to screen for cervical abnormalities caused by other HPV strains.

5. In caring for an adolescent with severe abdominal pain due to appendicitis, where should the nurse identify as McBurney's point?

• A. Right lower quadrant
• B. Left lower quadrant
• C. Right upper quadrant
• D. Left upper quadrant

Correct answer: A

Rationale: McBurney's point is located in the right lower quadrant of the abdomen, specifically between the umbilicus and the anterior iliac crest. This point is significant in diagnosing appendicitis, as tenderness at McBurney's point is a classic sign of appendicitis and indicates inflammation near the appendix. Therefore, the correct answer is the 'Right lower quadrant.' Choices B, C, and D are incorrect because McBurney's point is not located in the left lower quadrant, right upper quadrant, or left upper quadrant of the abdomen.
