Question 1 of 5

The nurse is caring for a client diagnosed with heart failure who is taking digoxin (Lanoxin). Which sign of digoxin toxicity should the nurse monitor for?

Correct Answer: B

Rationale: The correct answer is B: Bradycardia. Bradycardia is a common sign of digoxin toxicity, as digoxin can cause decreased heart rate. Therefore, monitoring the client for signs of bradycardia is crucial. Choices A, C, and D are incorrect. Hypertension is not typically associated with digoxin toxicity; instead, hypotension may occur. Hyperglycemia is not a common sign of digoxin toxicity. Insomnia is also not a typical sign of digoxin toxicity; instead, some patients may experience visual disturbances, confusion, or other neurological symptoms.

Question 2 of 5

The healthcare provider is evaluating the effects of care for a client with deep vein thrombosis (DVT). Which limb observations should the provider note as indicating the least success in meeting the outcome criteria for this problem?

Correct Answer: A

Rationale: Significant pedal edema, indicated by 3+, suggests ongoing or worsening venous insufficiency. This can be a sign that the care provided has not been effective in managing the deep vein thrombosis (DVT) and the associated complications. Monitoring and addressing pedal edema is crucial in the evaluation of DVT treatment outcomes and overall patient care. Choices B, C, and D are not indicative of the least success in meeting the outcome criteria for DVT. Slight residual calf tenderness, skin warmth, and a slightly larger calf girth do not necessarily point towards treatment failure or lack of improvement in DVT management.

Question 3 of 5

A client admitted with coronary artery disease (CAD) reports dyspnea at rest. What intervention should the nurse prioritize?

Correct Answer: B

Rationale: In a client with coronary artery disease (CAD) experiencing dyspnea at rest, the priority intervention should be to elevate the head of the bed to at least 45 degrees. This position helps reduce the work of breathing, optimizes lung expansion, and can alleviate symptoms of dyspnea by improving oxygenation and ventilation. Providing a walker for ambulation, monitoring oxygen saturation, and having an oxygen cannula at the bedside are important interventions but not the priority when the client is experiencing dyspnea at rest. Elevating the head of the bed is crucial to improve respiratory function and should be prioritized in this situation.

Question 4 of 5

The client with atrial fibrillation is receiving warfarin (Coumadin). Which laboratory test should be monitored to determine the effectiveness of the therapy?

Correct Answer: A

Rationale: Monitoring Prothrombin time (PT) and international normalized ratio (INR) is crucial when a client is on warfarin therapy. These tests assess the clotting ability of the blood and help determine the appropriate dosage of warfarin to prevent complications such as bleeding or clotting events. PT and INR values within the therapeutic range indicate the effectiveness of warfarin in managing atrial fibrillation. Choice B, activated partial thromboplastin time (aPTT), is not typically used to monitor warfarin therapy; it is more commonly used to assess the effectiveness of heparin therapy. Choice C, complete blood count (CBC), does not directly assess the anticoagulant effect of warfarin. Choice D, fibrinogen level, is not a primary test for monitoring warfarin therapy; it is more relevant in assessing conditions like disseminated intravascular coagulation.

Question 5 of 5

The client is being taught about the use of sublingual nitroglycerin for chest pain. Which instruction should be provided?

Correct Answer: B

Rationale: The correct method for administering sublingual nitroglycerin is to place the tablet under the tongue and allow it to dissolve. This route of administration facilitates rapid absorption of the medication into the bloodstream, enabling quick relief of chest pain associated with angina or heart conditions. Choice A is incorrect because sublingual nitroglycerin should not be swallowed whole. Choice C is wrong as chewing the tablet can lead to the rapid release of the drug, causing adverse effects like headaches or dizziness. Choice D is also incorrect as the tablet should not be placed between the cheek and gum, but under the tongue for proper absorption.
