1. A client is taking phenytoin (Dilantin) for seizure control, and a sample for a serum drug level is drawn. Which of the following indicates a therapeutic serum drug range?

Correct answer: B

Rationale: The correct therapeutic serum drug level range for phenytoin (Dilantin) is 10 to 20 mcg/mL. This range is considered optimal for seizure control while minimizing the risk of toxicity. Monitoring drug levels helps ensure that the client is within the therapeutic range for effective treatment.

2. A nurse preparing a client for surgery reviews the client's medication record. The client is to be nothing per mouth (NPO) after midnight. Which of the following medications, if noted on the client's record, should the nurse question?

Correct answer: D

Rationale: Prednisone is a corticosteroid that can cause adrenal atrophy, reducing the body's ability to withstand stress. During surgery, the dosage may need to be adjusted due to its impact on the body's stress response. Choices A, B, and C are not typically contraindicated before surgery and do not have the same potential impact on the body's stress response.

3. A healthcare professional is preparing to administer an intramuscular dose of penicillin to a client with a history of anaphylactic reactions to penicillin. Which action should the healthcare professional take first?

Correct answer: B

Rationale: When dealing with a client who has a history of anaphylactic reactions to penicillin, the priority action for the healthcare professional is to have an epinephrine injection readily available in case of a severe allergic reaction. In such cases, the immediate focus is on being prepared to manage a potentially life-threatening situation. While checking the medication order for accuracy, administering a test dose, and asking the client about allergies are essential steps in medication administration, the first priority is ensuring the availability of epinephrine to address a severe allergic reaction promptly.

4. A client with chronic renal failure is receiving ferrous sulfate (Feosol). The nurse monitors the client for which common side effect associated with this medication?

Correct answer: D

Rationale: Constipation is a common side effect of iron supplements such as ferrous sulfate. Iron can cause constipation by slowing down the movement of the digestive system and hardening the stool. Patients should be advised to increase their fluid intake, dietary fiber, and physical activity to help alleviate this side effect. Diarrhea (Choice A) is not a common side effect associated with ferrous sulfate. Weakness (Choice B) and headache (Choice C) are not typically linked to this medication.

5. A client is prescribed nitroglycerin (Nitro-Dur) transdermal patch for angina. Which instruction should the nurse include in the client's teaching plan?

Correct answer: C

Rationale: The correct instruction for the nurse to include in the client's teaching plan is to apply the nitroglycerin (Nitro-Dur) transdermal patch at the same time each day. This consistency helps maintain steady blood levels of the medication. While it is important to apply the patch to a hairless area of the skin for proper absorption, it does not necessarily have to be left on for 24 hours; typically, it is worn for 12-14 hours to allow for a nitrate-free period and reduce tolerance. Additionally, the patch can generally be kept on while taking a shower, as water exposure does not typically affect its efficacy.
