Nursing Elites

1. Which assessment data would cause suspicion that a 3-year-old child has Hirschsprung disease?

• A. Clay-colored stools and dark urine
• B. History of early passage of meconium in the newborn period
• C. History of chronic, progressive constipation and failure to gain weight
• D. Continual bouts of foul-smelling diarrhea

Correct answer: C

Rationale: Hirschsprung disease is characterized by chronic, progressive constipation and failure to gain weight. These symptoms are indicative of the disorder due to the absence of ganglion cells in the distal colon, leading to impaired motility and obstruction.

2. Which medication is most likely to cause serious respiratory depression as a potential adverse reaction?

• A. Morphine
• B. Pentazocine
• C. Hydrocodone
• D. Nalmefene

Correct answer: A

Rationale: Morphine, as a strong opioid agonist, has the highest likelihood of causing serious respiratory depression due to its potent effects on the central nervous system. While Pentazocine and Hydrocodone can also cause respiratory depression, they are less likely to do so compared to morphine. Nalmefene, an opioid antagonist, is used to reverse respiratory depression caused by opioids rather than causing it.

3. 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.

4. When developing a home program for self-care, which approach is the most effective?

• A. Require the parent to practice the steps regularly and track progress.
• B. Introduce new home programs weekly with clear instructions for the parent to follow.
• C. List all the steps and have the parent teach them to the child without practicing.
• D. Practice the new steps until the child is ready to independently perform them at home.

Correct answer: D

Rationale: The most effective approach when developing a home program for self-care is to practice the new steps with the child until they are capable of independently carrying them out at home. This method ensures that the child has mastered the skills before transitioning to independent implementation. It is essential for the child's success in self-care activities and promotes their autonomy and confidence. Requiring the parent to practice the steps regularly and track progress, introducing new programs weekly, or having the parent teach the steps without practice may not be as beneficial in fostering the child's independence and skill acquisition.

5. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.
