An important outcome of care for a female client with hypertension has been met when the client is able to do which of the following?

Correct Answer: A

Rationale: The correct answer is A: Return to her usual activities of daily living. This outcome indicates successful management of hypertension, as it implies that the client's blood pressure is controlled and stable enough for her to resume normal activities without significant limitations. This reflects a holistic approach to care, focusing on improving the client's quality of life. Explanation for other choices: B: Identifying actions to counteract risk factors is important but doesn't necessarily indicate that the client's hypertension is well managed. C: Lowering blood pressure by a specific percentage is not as meaningful as the client being able to function normally in daily life. D: Discontinuing lifestyle modifications would be detrimental as lifestyle changes are crucial for managing hypertension effectively.

Correct Answer: B

Rationale: The correct answer is B: A junctional rhythm. In a junctional rhythm, the atrioventricular (AV) node takes over as the pacemaker, resulting in the absence of P waves. The other components (QRS complex and T waves) are normal, indicating a regular ventricular depolarization and repolarization. A normal sinus rhythm (choice A) would have visible P waves preceding each QRS complex. Atrial fibrillation (choice C) would show irregularly irregular rhythm with no discernible P waves. A ventricular rhythm (choice D) would display wide QRS complexes and lack preceding P waves.

Correct Answer: B

Rationale: The correct sign for cardiac tamponade is Beck's triad, which consists of hypotension, distant heart sounds, and elevated jugular venous pressure. This is due to the compression of the heart by fluid in the pericardial sac. Shortness of breath (A) can be a symptom of many heart conditions, but is not specific to cardiac tamponade. Holosystolic murmur (C) is more indicative of mitral regurgitation. Bounding peripheral pulse (D) is seen in conditions like aortic regurgitation, not cardiac tamponade.

Correct Answer: B

Rationale: The correct answer is B: Give Digibind as an antidote. Digibind is the specific antidote for digoxin toxicity as it binds to digoxin and removes it from the body. This action helps to rapidly reduce the levels of digoxin in the system, counteracting the toxic effects. Checking a potassium level (A) may be important but not the priority when severe toxicity is present. Changing the dosing schedule (C) or giving a potassium supplement (D) will not address the immediate life-threatening effects of severe digoxin toxicity. Digibind is the most appropriate and urgent action to take in this scenario.

Correct Answer: B

Rationale: Correct Answer: B - The blood sugar drops due to impaired production of glucose from glycogen. Rationale: 1. Non-cardio-selective beta blockers inhibit beta-2 receptors in the liver. 2. Beta-2 receptors stimulate glycogenolysis, converting glycogen to glucose. 3. Inhibition of glycogenolysis leads to impaired production of glucose from glycogen. 4. Consequently, blood sugar levels decrease due to reduced availability of glucose. Summary of Other Choices: A: Incorrect. Non-cardio-selective beta blockers inhibit glycogenolysis, leading to decreased breakdown of glycogen and reduced glucose production, resulting in lower blood sugar levels. C: Incorrect. Non-cardio-selective beta blockers do affect blood sugar by impairing glucose production from glycogen. D: Incorrect. Non-cardio-selective beta blockers do not increase cellular uptake of glucose, but rather decrease glucose production from glycogen.
