Nursing Elites

1. The healthcare provider is screening children at a local community health clinic for infectious diseases. Which child is at the highest risk for hepatitis B virus?

• A. a newborn
• B. a 3-year-old
• C. a 7-year-old
• D. an 11-year-old

Correct answer: A

Rationale: Newborns are at the highest risk for hepatitis B virus due to potential transmission from the mother. The hepatitis B virus can be transmitted from an infected mother to her baby during childbirth. Children born to mothers infected with hepatitis B are at the highest risk of acquiring the infection. Choices B, C, and D are at lower risk compared to a newborn as they are less likely to have been exposed to the virus during childbirth.

2. The nurse is caring for a child who has just returned from surgery following a tonsillectomy and adenoidectomy. Which action by the nurse is appropriate?

• A. Offer ice chips every 2 hours
• B. Place the child in a semi-Fowler's position
• C. Encourage the child to drink from a cup
• D. Observe swallowing patterns

Correct answer: D

Rationale: Observing swallowing patterns is crucial post-tonsillectomy and adenoidectomy to detect signs of bleeding. Offering ice chips instead of ice cream helps prevent throat irritation. Placing the child in a semi-Fowler's position promotes airway patency and reduces the risk of aspiration. Encouraging the child to drink from a cup instead of a straw minimizes the risk of dislodging the surgical site.

3. Which of the following measures the proportion of the population that exhibits a particular disease at a particular time and includes both new and old cases?

• A. proportionate morbidity rate
• B. case fatality rate
• C. incidence ratio
• D. prevalence ratio

Correct answer: D

Rationale: The correct answer is D, prevalence ratio. Prevalence ratio measures the proportion of the population with a particular disease at a specific time, including both new and existing cases. Choice A, proportionate morbidity rate, is not a standard term and might confuse students. Choice B, case fatality rate, measures the proportion of deaths from a specific disease compared to the total number of cases but does not include both new and old cases. Choice C, incidence ratio, measures the rate of new cases of a disease in a specific population over a defined period, not considering existing cases.

4. A client with peptic ulcer disease is receiving ranitidine (Zantac). The nurse should monitor the client for which of the following side effects?

• A. Hypertension
• B. Constipation
• C. Diarrhea
• D. Hypotension

Correct answer: C

Rationale: The correct answer is C: Diarrhea. Ranitidine, which is used to treat peptic ulcer disease, can lead to gastrointestinal disturbances such as diarrhea. Choices A, B, and D are incorrect. Hypertension and hypotension are not common side effects of ranitidine. Constipation is also not a typical side effect associated with ranitidine use.

5. The client with acute hypocalcemia is admitted to the unit. Nursing action should include:

• A. Implement seizure precautions
• B. Assess for hypoglycemia
• C. Monitor for visual changes
• D. Observe for muscle weakness

Correct answer: A

Rationale: The correct action for a client with acute hypocalcemia is to implement seizure precautions. Hypocalcemia can lead to tetany and seizures due to neuromuscular irritability. Assessing for hypoglycemia (choice B) is not directly related to hypocalcemia. Monitoring for visual changes (choice C) is more indicative of conditions like hyperglycemia or retinal disorders. Observing for muscle weakness (choice D) is a common symptom of hypocalcemia but does not address the immediate risk of seizures, which is why implementing seizure precautions is the priority nursing action.
