Nursing Elites

1. In a client with congestive heart failure, the nurse would be correct in withholding a dose of digoxin without specific instruction from the healthcare provider if the client's

• A. serum digoxin level is 1.5 ng/mL.
• B. blood pressure is 104/68 mmHg.
• C. serum potassium level is 3 mEq/L.
• D. apical pulse is 68/min.

Correct answer: C

Rationale: The correct answer is C. Hypokalemia can precipitate digitalis toxicity in individuals on digoxin, increasing the risk of dangerous dysrhythmias. A serum potassium level of 3 mEq/L is below the normal range (3.5 to 5.5 mEq/L) and indicates hypokalemia, which can potentiate the effects of digoxin. Choices A, B, and D are not directly related to the potential for digitalis toxicity. Serum digoxin level of 1.5 ng/mL is within the therapeutic range, blood pressure of 104/68 mmHg is not a contraindication for administering digoxin, and an apical pulse of 68/min is within the normal range and not a reason to withhold digoxin.

2. The client with peripheral artery disease has been prescribed clopidogrel (Plavix). The nurse understands that more teaching is necessary when the client states which of the following?

• A. I should not be surprised if I bruise more easily or if my gums bleed a little when brushing my teeth.
• B. It is important to take this medicine with food to enhance its effectiveness and minimize stomach upset.
• C. I should stop taking Plavix if it makes me feel weak and dizzy.
• D. The doctor prescribed this medicine to make my platelets less likely to stick together and help prevent clots from forming.

Correct answer: C

Rationale: The correct answer is C. Weakness, dizziness, and headache are common adverse effects of Plavix and should be reported. It is essential to consult a physician before stopping Plavix as it plays a crucial role in preventing platelets from sticking together and forming clots. Choices A, B, and D are incorrect. Choice A is a common side effect of Plavix and does not indicate a need for further teaching. Choice B is incorrect because taking Plavix with or without food can affect its absorption and effectiveness. Choice D correctly explains the purpose of prescribing Plavix to prevent clot formation.

3. How can a nurse best help a client undergoing a bone marrow aspiration and biopsy, along with two upset family members, manage anxiety during the procedure?

• A. Allow the client's family to stay for emotional support.
• B. Accompany the client silently.
• C. Encourage the client to take slow, deep breaths to promote relaxation.
• D. Provide the client an opportunity to verbalize emotions.

Correct answer: C

Rationale: Encouraging the client to take slow, deep breaths is an effective way for the nurse to help the client manage anxiety during the bone marrow aspiration and biopsy procedure. Slow, deep breathing can promote relaxation and help reduce anxiety levels. Choice A, allowing the client's family to stay for emotional support, may provide comfort but does not address a direct intervention to help manage anxiety. Choice B, staying with the client silently, may not actively help the client address their anxiety. Choice D, allowing the client to express feelings, is important but may not directly address anxiety management during the procedure.

4. In a patient with deep vein thrombosis (DVT), which of the following symptoms would be expected?

• A. Chest pain.
• B. Shortness of breath.
• C. Coughing up blood.
• D. Cyanosis.

Correct answer: B

Rationale: Shortness of breath is a common symptom of deep vein thrombosis (DVT) due to the risk of a pulmonary embolism. DVT occurs when a blood clot forms in a deep vein, usually in the legs. If a portion of the clot breaks loose and travels to the lungs, it can cause a pulmonary embolism, leading to symptoms like shortness of breath. Chest pain is more commonly associated with conditions like a heart attack or pulmonary embolism itself. Coughing up blood is a symptom more indicative of conditions such as pulmonary embolism or lung cancer. Cyanosis, which is a bluish discoloration of the skin or mucous membranes due to poor oxygenation, can be seen in severe cases of pulmonary embolism but is not a typical symptom of DVT.

5. A patient taking trimethoprim-sulfamethoxazole (TMP-SMX) to treat a urinary tract infection complains of a sore throat. The nurse will contact the provider to request an order for which laboratory test(s)?

• A. Complete blood count with differential
• B. Throat culture
• C. Urinalysis
• D. Coagulation studies

Correct answer: A

Rationale: When a patient taking trimethoprim-sulfamethoxazole (TMP-SMX) for a urinary tract infection presents with a sore throat, the nurse should request a complete blood count with differential. TMP-SMX can cause life-threatening adverse effects such as agranulocytosis, a condition characterized by a low white blood cell count, which can manifest as a sore throat. Ordering a complete blood count with differential helps assess the patient's white blood cell count to detect any potential serious adverse effects. Throat culture (Choice B) is not indicated unless there are specific signs of a throat infection. Urinalysis (Choice C) is not relevant for assessing a sore throat. Coagulation studies (Choice D) are not typically indicated for a sore throat symptom.
