Correct Answer: B

Rationale: In this scenario, it is concerning that a patient under suicide watch is happy about being discharged as it may indicate that the patient's suicide plan has advanced. This change in behavior should be taken seriously as it can signal an increased risk of self-harm. Choices A, C, and D are less likely as the patient's happiness about discharge in this context is more indicative of a worsening situation rather than positive outcomes like being around family, clarifying future plans, or improving mood.

Correct Answer: C

Rationale: When a client is receiving drug therapy with furosemide and digitalis, the nurse should anticipate the development of hypokalemia due to the potassium-wasting effects of furosemide. Hypokalemia can potentiate digitalis toxicity. While hyperkalemia is a concern with some medications, it is not typically associated with furosemide and digitalis. Furosemide can lead to hyponatremia, not hypernatremia, due to its diuretic effect. Hypomagnesemia, though a possible imbalance, is not the most likely to occur in this scenario as furosemide and digitalis are more commonly associated with hypokalemia.

Correct Answer: A

Rationale: When teaching a client about anti-retroviral therapy for HIV, it is crucial to emphasize that therapy must not be interrupted to prevent viral resistance. HIV mutates rapidly, and any interruption can lead to the emergence of resistant strains, compromising treatment effectiveness. Choice B is incorrect because keeping the virus in check with anti-retrovirals helps the client's immune system fight off opportunistic infections. Choices C and D are incorrect because therapy should not be interrupted for any reason. If toxicity occurs, the healthcare provider may adjust the treatment regimen by prescribing alternative anti-retroviral drugs.

Correct Answer: C

Rationale: The correct answer is 6 years old. At this age, children typically have the potential for 20/20 vision. This is considered the standard age for achieving optimal vision clarity. Choices A, B, and D are incorrect as they are not typically associated with the age at which children achieve 20/20 vision.

Correct Answer: C

Rationale: Monitoring Jackie's cardiac status is of the highest priority in a patient with rheumatic fever. Rheumatic fever can lead to permanent cardiac damage, making it crucial to closely monitor the heart. Assessing for signs of carditis, such as murmurs or other cardiac symptoms, is essential. The second priority is evaluating joint symptoms for the presence of polyarthritis and pain, which are common manifestations of rheumatic fever. While assessing Jackie's response to hospitalization is important for her emotional well-being, it is not the highest priority. The presence of a macular rash, although relevant, is not as high a priority as monitoring cardiac status or assessing joint symptoms.
