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. A client with which of the following conditions is at risk for developing a high ammonia level?

• A. renal failure
• B. psoriasis
• C. lupus
• D. cirrhosis

Correct answer: D

Rationale: A client with cirrhosis is at risk for developing a high ammonia level due to impaired liver function. The liver normally converts ammonia into urea for excretion. In cirrhosis, this process is compromised, leading to elevated ammonia levels in the blood. Renal failure, psoriasis, and lupus do not typically cause high ammonia levels. Renal failure affects kidney function, while psoriasis and lupus are autoimmune conditions that do not directly impact ammonia metabolism.

3. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.

4. Following a classic cholecystectomy resection for multiple stones, the PACU nurse observes serosanguinous drainage on the dressing. The most appropriate intervention is to:

• A. notify the physician of the drainage.
• B. change the dressing.
• C. reinforce the dressing.
• D. apply an abdominal binder

Correct answer: C

Rationale: Serosanguinous drainage is expected after a classic cholecystectomy resection. The appropriate intervention is to reinforce the dressing to maintain pressure and promote clot formation. Changing the dressing prematurely increases the risk of infection as it disturbs the wound. Applying an abdominal binder is not indicated as it can interfere with visualizing the dressing and assessing for any signs of bleeding or infection. Notifying the physician is not necessary at this point unless there are signs of excessive bleeding or other concerning symptoms.

5. How should the LPN document pain for a non-verbal client using the FLACC pain scale with these findings?

• A. 1
• B. 4
• C. 3
• D. 2

Correct answer: B

Rationale: The correct answer is B: '4'. The FLACC pain scale assesses pain in non-verbal patients based on five categories: Face, Legs, Activity, Cry, and Consolability. In this case, the client exhibits occasional grimacing (1 point), relaxed legs (0 points), squirming (1 point), moans and whimpers (1 point), and is distractible (1 point). Adding these points together results in a total pain score of 4. Therefore, the LPN should document a pain score of 4 for this non-verbal client. Choices A, C, and D are incorrect as they do not accurately reflect the total pain score based on the given findings.
