Correct Answer: A

Rationale: The correct answer is A: Avoid potassium-rich foods. Spironolactone can lead to hyperkalemia, a condition characterized by high levels of potassium in the blood. To prevent this complication, clients taking spironolactone should avoid potassium-rich foods. Choice B is incorrect because spironolactone can be taken with or without food. Choice C is not directly related to spironolactone use, as toxicity monitoring is not a specific concern with this medication. Choice D is incorrect because discontinuing the medication solely based on elevated potassium levels may not be necessary; instead, dosage adjustments or potassium restriction are often more appropriate.

Correct Answer: A

Rationale: A TPN solution with an oily appearance and a layer of fat on top indicates that the solution is 'cracked' and should not be used as it may have separated or deteriorated. This finding suggests a need to obtain a new bag of TPN before administering. Options B, C, and D are normal aspects of TPN administration. Option B confirms the presence of essential components in the TPN solution, option C provides information about the preparation time, and option D ensures proper identification and matching of the TPN with the correct client.

Correct Answer: A

Rationale: Corrected Rationale: When educating a client about fluoxetine, it is essential to mention that it can take several weeks for the therapeutic effects to be noticed. This is because fluoxetine is an SSRI that requires time to build up in the body and start producing its intended effects. Choice B is incorrect as fluoxetine is not an antipsychotic medication but an SSRI. Choice C is inaccurate because fluoxetine can be taken at any time of the day, and there is no specific requirement to take it at night. Choice D is incorrect as all medications, including fluoxetine, have potential side effects that should be discussed with the client.

Correct Answer: B

Rationale: When a patient has extensive burns involving the head, neck, and chest, the priority concern is airway obstruction. The proximity of the burns to the airway can lead to swelling and compromise the patient's ability to breathe. In this situation, ensuring a clear airway and adequate oxygenation takes precedence over other risks such as infection, fluid imbalance, or pain management. While these are also important considerations in burn care, the immediate threat to the patient's life from airway compromise makes it the priority for assessment and intervention.

Correct Answer: A

Rationale: Naloxone is the correct answer. Naloxone is the antidote for opioid overdose, including hydromorphone. Opioids can cause respiratory depression, and a significant decrease in respiratory rate from 16 to 6 breaths per minute indicates respiratory compromise. Naloxone should be administered promptly to reverse the effects of the opioid and restore normal respiratory function. Flumazenil (Choice B) is used to reverse the effects of benzodiazepines, not opioids. Activated charcoal (Choice C) is used for gastrointestinal decontamination in cases of overdose with certain substances, but it is not the appropriate intervention for opioid-induced respiratory depression. Aluminum hydroxide (Choice D) is an antacid and has no role in managing opioid overdose or respiratory depression.
