A nurse is caring for a patient with asthma who is using a metered-dose inhaler (MDI). The nurse should instruct the patient to:

Correct Answer: D

Rationale: The correct answer is D: Hold the breath for at least 5 seconds after inhaling the medication. Holding the breath after inhaling the medication allows for better absorption of the medication into the lungs. This helps ensure the medication reaches the target area for optimal effectiveness. Exhaling deeply before using the inhaler (Choice A) is not necessary and can actually reduce the amount of medication reaching the lungs. Using the inhaler only when asthma symptoms are severe (Choice B) is not recommended as it is important to use the inhaler as prescribed by the healthcare provider. Inhaling deeply while activating the inhaler (Choice C) is important, but holding the breath after inhaling the medication is crucial for optimal medication delivery.

Correct Answer: B

Rationale: The correct answer is B: Deep vein thrombosis (DVT). Patients with a history of stroke are at increased risk for DVT due to immobility and vascular damage. Monitoring for DVT is crucial to prevent life-threatening complications like pulmonary embolism. Acute renal failure (A) is not directly related to stroke and is not a common complication. Pneumonia (C) may occur but is not the highest priority compared to DVT. Hypertension (D) is important to monitor but is not the priority in this case as DVT poses a more immediate risk to the patient's health.

Correct Answer: A

Rationale: Correct answer: A - Hyperkalemia Rationale: 1. In CKD, impaired kidney function leads to decreased potassium excretion, causing hyperkalemia. 2. Hyperkalemia can result in life-threatening cardiac arrhythmias. 3. Monitoring potassium levels is crucial in CKD management. Summary: B: Hypoglycemia - Not typically associated with CKD, more common in diabetes. C: Hyperglycemia - Common in diabetes, but not a typical complication of CKD. D: Hypercalcemia - Uncommon in CKD, more often seen in hyperparathyroidism.

Correct Answer: C

Rationale: The correct answer is C because monitoring kidney function with regular laboratory tests is crucial in managing CKD. Regular testing helps identify changes in kidney function early, allowing for timely interventions to prevent complications. Administering diuretics (choice A) may worsen kidney function. Encouraging weight loss (choice B) may be necessary, but monitoring kidney function takes precedence. Encouraging the patient to limit fluid intake (choice D) may be necessary in some cases, but it is not the priority intervention.

Correct Answer: A

Rationale: The correct answer is A: Shortness of breath and weight gain. In chronic heart failure, fluid overload can lead to pulmonary congestion, causing shortness of breath. Weight gain is also a key sign of fluid retention. Increased urine output and hypotension (choice B) are more indicative of dehydration. Fatigue and dizziness (choice C) can be nonspecific symptoms and not directly related to fluid overload. Dry mouth and thirst (choice D) are symptoms of dehydration rather than fluid overload in chronic heart failure. Monitoring for shortness of breath and weight gain allows for early detection and intervention in managing fluid overload in patients with chronic heart failure.
