1. Which of the following represents a normal serum potassium level?

• A. 1.5 mEq/L
• B. 3.0 mEq/L
• C. 4.0 mEq/L
• D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

2. Which of the following medications should be held 24-48 hours prior to an electroencephalogram (EEG)?

• A. Lasix (furosemide)
• B. Cardizem (diltiazem)
• C. Lanoxin (digoxin)
• D. Dilantin (phenytoin)

Correct answer: D

Rationale: Anticonvulsants like Dilantin should be held 24-48 hours before an EEG to prevent interference with the test results. Medications such as tranquilizers, barbiturates, and other sedatives should also be avoided. Lasix, Cardizem, and Lanoxin do not belong to these categories and are not known to interfere with EEG results.

3. 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.

4. The nurse and a colleague are on the elevator after their shift, and they hear a group of healthcare providers discussing a recent client scenario. Which client right might be breached?

• A. right to refuse treatment
• B. right to continuity of care
• C. right to confidentiality
• D. right to reasonable responses to requests

Correct answer: C

Rationale: The right to confidentiality of client information might be breached when client care situations are discussed in public areas or without regard to maintaining the information as private and confidential. In this scenario, the conversation on the elevator could lead to a breach of the client's right to confidentiality. The other options, such as the right to refuse treatment, right to continuity of care, and right to reasonable responses to requests, are not being breached in this instance, making them incorrect choices.

5. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

• A. blood urea nitrogen
• B. serum calcium
• C. serum ammonia
• D. serum creatinine

Correct answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.
