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 potential damage to blood vessels. Monitoring for DVT is crucial to prevent life-threatening complications like pulmonary embolism. Pulmonary embolism (A) is a potential complication of DVT but not the most direct concern. Hypertension (C) is a common condition but not directly linked to a history of stroke. Hyperglycemia (D) is more commonly associated with diabetes rather than stroke history. Monitoring for DVT in stroke patients is essential for early detection and intervention.

Correct Answer: A

Rationale: The correct answer is A: Psoriasis. Psoriasis is characterized by red, scaly patches on the skin, which align with the symptoms described. Psoriasis commonly affects the lower legs and is associated with severe itching. Eczema (choice B) is characterized by red, inflamed, and itchy skin patches, but typically presents differently from psoriasis. Contact dermatitis (choice C) is a localized reaction that occurs when the skin comes into contact with an irritant or allergen, and fungal infections (choice D) typically present with itching, redness, and sometimes peeling skin, but not necessarily scaly patches like psoriasis.

Correct Answer: D

Rationale: The correct answer is D because clients with renal disease may have impaired kidney function, leading to difficulty in regulating potassium levels. High potassium intake can further burden the kidneys, potentially causing hyperkalemia. Clients on diuretic therapy (choice A) may actually need to monitor potassium levels due to potential electrolyte imbalances. Clients with an ileostomy (choice B) typically do not have issues with potassium absorption. Clients with metabolic alkalosis (choice C) may have potassium shifts but do not necessarily need to avoid high-potassium foods unless specifically advised by their healthcare provider.

Correct Answer: A

Rationale: The correct answer is A: Transfuse neutrophils. Neutrophil transfusion is not a standard treatment for neutropenia as neutrophils do not survive well outside the body. For the other choices: B: Excluding raw vegetables is correct to prevent infection. C: Avoiding rectal suppositories is correct to prevent mucosal injury. D: Prohibiting vases of fresh flowers is correct to prevent exposure to fungal spores. So, transfusing neutrophils is inappropriate as it is not a standard treatment for neutropenia.

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.
