Correct Answer: B

Rationale: The correct answer is B: Do not use underarm deodorant. This is important because deodorant can interfere with the mammogram results, leading to false readings. It is crucial to have a clean and uncontaminated image for an accurate diagnosis. Choice A is incorrect as it can affect the quality of the mammogram. Choices C and D are irrelevant to the mammography procedure and not necessary instructions for the client.

Correct Answer: D

Rationale: The correct answer is D. A client with renal disease must avoid foods high in potassium to prevent hyperkalemia, as the kidneys are unable to properly filter and excrete potassium. Foods high in potassium can lead to dangerous levels of potassium in the blood, which can be life-threatening for individuals with renal disease. Choice A is incorrect because a client receiving diuretic therapy may actually need to increase their potassium intake due to the potassium-wasting effects of diuretics. Choice B is incorrect as having an ileostomy does not necessarily affect potassium levels. Choice C is incorrect because clients with metabolic alkalosis may actually benefit from consuming foods high in potassium to help correct the acid-base imbalance.

Correct Answer: A

Rationale: The priority nursing intervention for a client with asthma experiencing wheezing is to administer oxygen. Wheezing indicates airway constriction and decreased oxygenation, making oxygen crucial for adequate tissue perfusion. Administering oxygen helps improve oxygen levels, alleviate respiratory distress, and prevent hypoxemia. Applying a bronchodilator (Choice B) may be beneficial after oxygen is administered. Applying a cold compress (Choice C) is not indicated for asthma exacerbations, and encouraging deep breathing (Choice D) may worsen respiratory distress in a client with wheezing. In summary, administering oxygen is the priority intervention to address the immediate respiratory needs of the client with asthma and wheezing.

Correct Answer: B

Rationale: The correct answer is B: Edema and proteinuria. In CKD, the kidneys are unable to filter waste products effectively, leading to fluid retention (edema) and protein leaking into the urine (proteinuria). Edema occurs due to fluid buildup from decreased kidney function. Proteinuria is a result of damaged glomeruli in the kidneys, allowing proteins to leak into the urine. Weight loss and polyphagia (excessive hunger) are not typical symptoms of CKD. Hypertension and tachycardia can occur in CKD due to fluid overload and electrolyte imbalances. Hypothermia and bradycardia are not common symptoms of CKD and would be more indicative of other conditions.

Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. This is the nurse's first action for a client with a suspected MI because nitroglycerin helps dilate blood vessels, improving blood flow to the heart. This can help reduce chest pain and prevent further damage to the heart muscle. Administering nitroglycerin promptly is crucial in managing an MI. Monitoring cardiac rhythm (B) and assessing the ECG (C) are important steps, but administering nitroglycerin takes precedence in addressing the client's immediate symptoms. Assisting with positioning (D) is not as urgent or directly related to managing an MI compared to administering nitroglycerin.
