Correct Answer: B

Rationale: The correct instruction is to hold your breath for 10 seconds after inhaling the medication. This allows the medication to settle in the lungs and maximize its effectiveness. Choice A is incorrect as inhaling quickly may lead to improper medication delivery. Choice C is wrong because taking a second puff immediately after the first without waiting for the prescribed interval may cause an overdose. Choice D is also incorrect as exhaling fully after using the inhaler may result in the medication being exhaled rather than absorbed by the lungs.

Correct Answer: C

Rationale: The correct action the nurse should take when administering enoxaparin is to inject the medication in the abdomen subcutaneously. This route ensures proper absorption of the medication. Aspiration is not necessary before injecting enoxaparin as it is a subcutaneous injection, not an intramuscular injection. Massaging the site after injecting should be avoided to prevent bruising. Enoxaparin injections are typically given at a 45 to 90-degree angle, not necessarily at a strict 90-degree angle.

Correct Answer: A

Rationale: The correct answer is A. Clients with chronic kidney disease often develop anemia due to reduced erythropoietin production, leading to decreased red blood cell production. Iron supplementation is frequently required to enhance red blood cell production. Choices B, C, and D are incorrect because in chronic kidney disease, there is a need to restrict phosphorus intake, control carbohydrate intake for blood sugar management, and monitor electrolytes and fluid balance rather than blood glucose levels.

Correct Answer: D

Rationale: The correct answer is to have naloxone available in case of respiratory depression. Morphine is an opioid that can lead to respiratory depression, especially in higher doses. Naloxone is the antidote for opioid overdose and should be readily accessible when administering morphine to reverse respiratory depression if it occurs. Instructing the client to take a deep breath during administration (choice A) is not directly related to ensuring safety in this scenario. Administering the medication over 30 seconds (choice B) may help with the comfort of the client but does not address the potential risk of respiratory depression. Verifying the client's pain level (choice C) is important but not the primary action to ensure safety when administering morphine.

Correct Answer: A

Rationale: The correct answer is A. Tying wrist restraints to the bed rails is a safety hazard because if the bed rails are lowered, the restraints can tighten and cause injury or asphyxiation. Choice B, placing a bedside table across the foot of the bed, may not be ideal for convenience but does not pose a direct safety hazard. Choice C, leaving a meal tray at the bedside from breakfast, is more of an infection control issue than an immediate safety hazard. Choice D, having a call light extension cord pinned to the bedspread, is also not a direct safety hazard unless it poses a risk of entanglement or tripping, which is not indicated in the scenario.
