Nursing Elites

1. What sign might the nurse observe in a client with a high ammonia level?

• A. coma
• B. edema
• C. hypoxia
• D. polyuria

Correct answer: A

Rationale: Coma is a sign that a nurse might observe in a client with a high ammonia level. Elevated ammonia levels can lead to hepatic encephalopathy, a condition characterized by impaired brain function, which can progress to coma. Edema (choice B) is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia (choice C) is a condition of inadequate oxygen supply to tissues and is not directly related to high ammonia levels. Polyuria (choice D) refers to excessive urination and is not a typical sign of high ammonia levels.

2. Why might breast implants interfere with mammography?

• A. They might cause additional discomfort.
• B. They are contraindications to mammography.
• C. They are likely to be dislodged.
• D. They might prevent detection of masses.

Correct answer: D

Rationale: Breast implants can interfere with mammography by potentially preventing the detection of masses. The presence of implants can obscure a clear view of breast tissue, making it difficult to identify abnormalities such as masses that may indicate breast cancer. Choices A, B, and C are incorrect because discomfort, contraindications, and dislodgment are not primary reasons why breast implants interfere with mammography. The main concern is the impedance of detecting abnormalities accurately due to the implants.

3. What spinal change occurring with pregnancy alters mobility?

• A. Scoliosis.
• B. Kyphosis.
• C. Lordosis.
• D. Ankylosing spondylitis.

Correct answer: C

Rationale: The correct answer is 'Lordosis.' During pregnancy, the enlarging uterus places increased weight on the spine, causing an exaggerated inward curvature known as lordosis. This change alters mobility by shifting the center of gravity forward, leading to a compensatory change in posture. Scoliosis (choice A) is a sideways curvature of the spine, not typically associated with pregnancy. Kyphosis (choice B) is an exaggerated outward curvature of the spine, while ankylosing spondylitis (choice D) is a chronic inflammatory condition affecting the spine, neither of which are directly related to the spinal changes seen in pregnancy.

4. The LPN is caring for a client with an NG tube, and the RN administers evening medications through the NG tube. The client asks if he can lie down when the nurse leaves the room. What is the most appropriate response?

• A. You can lie down in 1 hour.
• B. You can lie down in 30 minutes if your NG residual is below 50 mL.
• C. You can lie down in about 30 minutes.
• D. Yes, feel free to lie down.

Correct answer: A

Rationale: After administering medication through an NG tube, the client should remain upright for 30 minutes to ensure proper absorption of the medications. Therefore, the most appropriate response is to advise the client to lie down in 1 hour. Choice B is incorrect because waiting only 30 minutes may not provide sufficient time for the medications to be fully absorbed, as the recommended time is 30 minutes. Choice C is misleading as it incorrectly suggests that lying down in about 30 minutes is acceptable, which could compromise medication effectiveness. Choice D is incorrect as it does not provide accurate information regarding the appropriate timing for lying down after NG tube medication administration, potentially leading to decreased medication absorption.

5. Which of the following client statements indicates adequate understanding of preparation for electroencephalography?

• A. "I don't need to eat or drink after midnight."?
• B. "I need to wash my hair before the test."?
• C. "I need to remove metal jewelry."?
• D. "I can't take aspirin before the test."?

Correct answer: B

Rationale: The correct statement is, 'I need to wash my hair before the test.' Washing the hair is necessary to remove hair products that could interfere with electrode attachment to the scalp. Restricting food or drink is not required, except for avoiding caffeinated beverages. Removing metal jewelry is unnecessary for an electroencephalography procedure. Aspirin does not need to be avoided before the test; medications like anticonvulsants, tranquilizers, barbiturates, and sedatives are the ones that might need to be held.
