Correct Answer: C

Rationale: The correct answer is to advise the client to apply ice to the breasts for comfort. Applying ice can help reduce swelling and discomfort associated with engorgement in a woman who is not breastfeeding. Expressing milk manually would stimulate further milk production, which is not desired in this case. Wearing a tight bra could increase discomfort by putting pressure on the engorged breasts. Warm showers may actually increase swelling due to the vasodilation effect of heat.

Correct Answer: B

Rationale: The correct answer is B: 'I should use my rescue inhaler when I start to experience wheezing.' A rescue inhaler is used during the onset of asthma symptoms, such as wheezing, to quickly open the airways. It is not intended for routine daily use or prevention, which is the role of a maintenance inhaler. Option A is incorrect because a rescue inhaler is not used for prevention but for immediate relief during an asthma attack. Option C is incorrect because the peak flow meter reading is used to monitor asthma control, not to determine when to use a rescue inhaler. Option D is incorrect because using a rescue inhaler only before going to bed does not address the need for immediate relief when wheezing or experiencing asthma symptoms.

Correct Answer: B

Rationale: Deep, rapid respirations (Kussmaul respirations) and lethargy are signs of diabetic ketoacidosis (DKA), which occurs in uncontrolled type 1 diabetes. Checking the blood glucose is the priority to confirm hyperglycemia and guide immediate treatment. Pulse oximetry is not the priority in this situation as the issue is related to altered glucose levels, not oxygenation. Arterial blood gases and serum electrolytes may be important later in the management of DKA but are not the initial priority compared to confirming and addressing the hyperglycemia.

Correct Answer: A

Rationale: The correct answer is to evaluate the client's swallowing ability. Osmotic demyelination can cause dysphagia, putting the client at risk for aspiration. Assessing swallowing function is crucial to prevent complications such as aspiration pneumonia. Reorienting the client frequently (Choice B) is more suitable for confusion related to conditions like delirium. Patching one eye (Choice C) is a technique used for diplopia or double vision, not specifically indicated for osmotic demyelination. Performing range of motion exercises (Choice D) may be beneficial for preventing complications of immobility but is not the priority intervention for osmotic demyelination.

Correct Answer: B

Rationale: Antibiotic ointment is ineffective against athlete's foot, which is a fungal infection. The nurse should instruct the mother to stop using the ointment and ensure the feet are dried properly, as moisture exacerbates fungal infections. Applying a different antifungal medication is a valid option, but addressing the moisture issue by drying the feet completely is the immediate priority. Continuing to use the antibiotic ointment or reapplying it for a longer period will not treat the fungal infection effectively.
