1. The client is starting therapy with digoxin (Lanoxin). What instruction should the nurse reinforce about the medication?

Correct answer: C

Rationale: The correct answer is C: 'Monitor for yellow or blurred vision.' When a client is taking digoxin, it is crucial to monitor for signs of toxicity, such as yellow or blurred vision, as these can indicate an adverse reaction. Reporting these visual disturbances promptly to the healthcare provider is important for further evaluation and management to prevent potential complications. Choices A, B, and D are incorrect because taking digoxin with meals, avoiding dairy products, or increasing potassium-rich foods are not specific instructions related to monitoring for adverse effects of digoxin therapy.

2. A client with a history of angina pectoris reports chest pain after climbing stairs. What should be the nurse's first action?

Correct answer: C

Rationale: The correct action for a client experiencing anginal pain, like chest pain after climbing stairs, is to sit the client down and have them rest. Resting reduces myocardial oxygen demand, which can help relieve anginal pain. Administering oxygen or nitroglycerin may be appropriate interventions after the client has been seated and rested. Checking the client's blood pressure is important but not the immediate priority when a client is experiencing anginal pain. Therefore, the first action should be to sit the client down and allow them to rest.

3. A client has a new prescription for metformin. Which of the following statements should the nurse include in the teaching?

Correct answer: C

Rationale: Increasing fluid intake is an important teaching point for clients starting metformin to prevent gastrointestinal discomfort, a common side effect of this medication. Metformin can cause gastrointestinal symptoms such as nausea, bloating, and diarrhea, which can be reduced by staying well-hydrated. Therefore, advising the client to increase their fluid intake will help minimize these side effects and improve medication tolerance. The other options are incorrect: Option A is a general instruction for taking medications but not specifically related to metformin. Option B is incorrect because metformin typically does not cause hypoglycemia but rather hyperglycemia. Option D is also incorrect as a metallic taste in the mouth is not a common side effect of metformin.

4. A client has a new prescription for transdermal nitroglycerin patches. Which of the following instructions should be included for proper use?

Correct answer: B

Rationale: Placing the nitroglycerin patch on an area of skin away from skin folds and joints is crucial to ensure optimal absorption and effectiveness of the medication. Placing the patch on skin folds or joints can interfere with absorption, potentially reducing the patch's efficacy. Therefore, it is essential to follow this instruction to maximize the therapeutic benefits of the nitroglycerin patches. The other options are incorrect because applying the patch to the same site each day can lead to skin irritation, keeping the patch on 24 hours per day may not be necessary depending on the specific patch instructions, and replacing the patch every 72 hours is not the standard frequency for nitroglycerin patches.

5. The healthcare provider is preparing to administer a beta blocker to a client with hypertension. What parameter should be checked before administering the medication?

Correct answer: B

Rationale: Before administering a beta blocker, it is crucial to check the apical pulse. Beta blockers have the potential to slow down the heart rate, making it essential to assess the pulse rate to ensure it is within the safe range before giving the medication. Checking the serum potassium level (choice A) is important when administering certain medications, but it is not specifically required before giving a beta blocker. Oxygen saturation (choice C) and pupil reaction to light (choice D) are not directly related to monitoring parameters for beta blocker administration.
