The client has hypertension and is being treated with an ACE inhibitor. What vital signs would trigger the release of renin from the kidneys?

Correct Answer: B

Rationale: The correct answer is B (BP of 145/95). When the blood pressure is elevated, the kidneys sense a decrease in perfusion pressure and trigger the release of renin to increase blood pressure. A low blood pressure of 70/40 (choice A) would not stimulate renin release as it is too low. The pulse rate (choices C & D) does not directly trigger the release of renin.

Correct Answer: A

Rationale: Aspirin is the correct answer as it inhibits platelet aggregation by irreversibly inhibiting cyclooxygenase enzyme. This prevents the formation of thromboxane A2, decreasing platelet activation. Pradaxa is a direct thrombin inhibitor, Heparin is an anticoagulant that inhibits thrombin and factor Xa, and Warfarin inhibits vitamin K-dependent clotting factors. Therefore, only Aspirin directly targets platelet function.

Correct Answer: C

Rationale: The correct answer is C because tissue plasminogen activator (TPA) promotes the conversion of plasminogen to plasmin. Plasmin is an enzyme that breaks down fibrin, the protein that forms blood clots. This mechanism helps dissolve blood clots, making it effective in treating conditions like stroke or heart attack caused by blood clots. Choice A is incorrect because TPA does not directly affect platelets, but instead targets the breakdown of clots. Choice B is incorrect as TPA does not work by inactivating clotting factors, but rather enhances clot breakdown. Choice D is incorrect because TPA does not block the synthesis of clotting factors, but rather enhances the breakdown of existing clots.

Correct Answer: A

Rationale: The correct answer is A: Dyazide. Dyazide is a combination medication of hydrochlorothiazide and triamterene, which are diuretics that help lower blood pressure by reducing fluid retention and decreasing blood volume. Metformin is primarily used for diabetes, Digoxin for heart conditions, and Warfarin for blood clotting. Therefore, only Dyazide directly affects blood pressure by targeting fluid balance.

Correct Answer: B

Rationale: The correct answer is B: Regular sinus rhythm. This ECG tracing shows a normal sinus rhythm with regular P waves preceding each QRS complex. The P waves are upright and consistent in morphology, indicating they originate from the SA node. The QRS complexes are narrow and follow a consistent pattern, demonstrating normal conduction through the AV node and ventricles. Sinus tachycardia (choice A) would show an elevated heart rate, sinus bradycardia (choice C) would show a slower heart rate, and frequent PVCs (choice D) would display premature and abnormal beats unrelated to the sinus node.
