Nursing Elites

1. A client with hypertension is prescribed metoprolol (Lopressor). The nurse should monitor the client for which side effect?

• A. Tachycardia
• B. Bradycardia
• C. Hypertension
• D. Hyperglycemia

Correct answer: B

Rationale: Metoprolol is a beta-blocker that works by slowing the heart rate. Therefore, the nurse should monitor the client for bradycardia, which is a potential side effect of metoprolol. Bradycardia refers to a heart rate that is slower than normal, and it can be a concern when administering medications like metoprolol that affect heart rate. Choices A, C, and D are incorrect as tachycardia (fast heart rate), hypertension (high blood pressure), and hyperglycemia (high blood sugar) are not typically associated with metoprolol use. In fact, metoprolol is used to treat hypertension and certain heart conditions by lowering heart rate and blood pressure.

2. When preparing to administer a controlled substance, which of the following actions is required?

• A. Check the client's identification bracelet.
• B. Check the client's allergy status.
• C. Have a second nurse witness disposal of the medication.
• D. Document the administration in the client's medical record.

Correct answer: C

Rationale: When administering controlled substances, it is crucial to have a second nurse witness the disposal of the medication. This measure ensures proper handling, reduces the risk of diversion, and promotes compliance with regulations regarding controlled substances. Having a second nurse witness the disposal is a safeguard to maintain accountability and prevent any potential misuse or errors during the disposal process. Checking the client's identification bracelet and allergy status are important steps in medication administration but are not specifically required for controlled substances. Documenting the administration in the client's medical record is essential but does not specifically relate to the disposal of controlled substances.

3. A client with a diagnosis of angina pectoris is prescribed nitroglycerin tablets. How should the nurse instruct the client to take the medication?

• A. Swallow the tablet whole with water
• B. Place the tablet under the tongue and let it dissolve
• C. Chew the tablet and then swallow
• D. Place the tablet between the cheek and gum

Correct answer: B

Rationale: Nitroglycerin is most effective when administered sublingually (under the tongue) as it is rapidly absorbed into the bloodstream. Placing the tablet under the tongue allows for quick absorption and faster relief of angina symptoms. Chewing the tablet, swallowing it, or placing it between the cheek and gum would not provide the same rapid onset of action needed during an angina episode. Therefore, the correct instruction for the client is to place the nitroglycerin tablet under the tongue and let it dissolve for optimal effectiveness.

4. A client has a new prescription for heparin. Which of the following laboratory results should be monitored to evaluate the effectiveness of the medication?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the laboratory result that should be monitored to evaluate the effectiveness of heparin. Heparin works by prolonging the aPTT, and monitoring this parameter helps ensure the medication's effectiveness and safety in preventing clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor the effectiveness of warfarin, another anticoagulant. Platelet count is essential to assess platelet function and clotting disorders, but it is not specifically used to monitor heparin therapy.

5. A client has a new prescription for phenytoin. Which of the following instructions should the nurse include?

• A. Take the medication with a full glass of water.
• B. Avoid consuming dairy products.
• C. Take the medication on an empty stomach.
• D. Expect a metallic taste in your mouth.

Correct answer: B

Rationale: The correct instruction for a client prescribed phenytoin is to avoid consuming dairy products. Dairy products can reduce the absorption of phenytoin. Taking the medication with a full glass of water (Choice A) is generally a good practice for oral medications but is not specifically required for phenytoin. Taking the medication on an empty stomach (Choice C) can lead to gastrointestinal upset, so it is not recommended for phenytoin. Expecting a metallic taste in the mouth (Choice D) is a possible side effect of phenytoin but is not a crucial instruction for the client to follow.
