Correct Answer: A

Rationale: In DKA, restoring fluid balance with sodium chloride is a priority to address the dehydration and electrolyte imbalances present in this condition. Choice B, preparing an emergency dose of glucagon, is incorrect because DKA is characterized by insulin deficiency, not glucagon deficiency. Choice C, determining the last time the client ate, is not the immediate priority in managing DKA. Choice D, checking urine for ketone bodies with a dipstick, may help confirm the diagnosis of DKA but is not the most critical intervention at this time.

Correct Answer: C

Rationale: Choice C is the best response because it directly addresses the client's expressed hopelessness and assesses the risk for self-harm. When a client with major depressive disorder expresses feeling worthless and unable to see improvement, it is essential to assess suicidal ideation to ensure their safety. Choices A, B, and D provide empathy and support, which are important but addressing suicidal ideation is the priority in this situation.

Correct Answer: C

Rationale: In a client with chronic heart failure receiving furosemide, crackles in the lungs indicate pulmonary congestion, requiring immediate intervention. This finding suggests fluid accumulation in the lungs, impairing oxygen exchange and potentially leading to respiratory distress. Monitoring and managing pulmonary congestion promptly are crucial to prevent worsening heart failure and respiratory compromise. The other options, while important to assess in a client with heart failure, do not indicate an immediate need for intervention like crackles in the lungs do. A heart rate of 60 beats per minute may be within the normal range for some individuals, a blood pressure of 110/70 mmHg is relatively stable, and peripheral edema is a common manifestation of heart failure that should be monitored but does not require immediate intervention compared to pulmonary congestion.

Correct Answer: C

Rationale: In a client with right-sided heart failure, crackles in the lungs are the most concerning finding as they indicate pulmonary congestion, which requires immediate intervention. Crackles suggest fluid accumulation in the lungs, leading to impaired gas exchange and potential respiratory distress. Jugular venous distention (Choice A) and peripheral edema (Choice B) are common findings in right-sided heart failure but do not indicate acute deterioration requiring immediate intervention. Elevated liver enzymes (Choice D) may be seen in chronic heart failure but do not warrant immediate action compared to the urgent need to address pulmonary congestion indicated by crackles in the lungs.

Correct Answer: A

Rationale: Offering alternative protein sources like dairy products and nuts can help maintain nutrition when the client finds certain foods unpalatable, as in this case where beef, chicken, and eggs taste 'bitter'. Encouraging smaller, more frequent meals may not address the issue of unpalatable foods. Offering nutritional supplements between meals may not specifically address the problem of protein intake. Discussing appetite stimulants should be considered after exploring less invasive options first.
