Nursing Elites

1. 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: Cirrhosis is the correct answer. In cirrhosis, the liver is unable to detoxify ammonia to urea, leading to an accumulation of ammonia in the blood. This can result in hepatic encephalopathy, a condition characterized by high ammonia levels affecting brain function. Renal failure (Choice A), psoriasis (Choice B), and lupus (Choice C) are not directly associated with an increased risk of high ammonia levels as seen in cirrhosis.

2. The LPN is checking for residual before administering enteral feeding through a PEG tube. Which of these steps is incorrect?

• A. The LPN elevates the head of the bed by at least 30 degrees.
• B. If the residual is greater than 200mL, the LPN should not administer the enteral feeding.
• C. The LPN should discard the residual before administering the tube feeding.
• D. The residual pH level is tested to ensure appropriate placement.

Correct answer: C

Rationale: The incorrect step is choice C. The residual should be discarded before administering the tube feeding. Discarding the residual is essential to prevent contamination and ensure accurate measurement of the enteral feeding. Elevating the head of the bed by at least 30 degrees (choice A) is correct as it helps prevent aspiration during feeding. Testing the pH level of the residual (choice D) ensures proper placement of the tube. Withholding feeding if the residual is greater than 200mL (choice B) is crucial to prevent overfeeding, making this statement correct.

3. Which of the following nursing diagnoses might be appropriate as Parkinson's disease progresses and complications develop?

• A. Impaired Physical Mobility
• B. Dysreflexia
• C. Hypothermia
• D. Impaired Dentition

Correct answer: A

Rationale: As Parkinson's disease progresses and complications develop, impaired physical mobility is a relevant nursing diagnosis due to symptoms like a shuffling gait and rigidity that can impair movement. Dysreflexia is not typically associated with Parkinson's disease; it is more commonly seen in spinal cord injuries. Hypothermia is a condition of low body temperature and is not directly related to Parkinson's disease progression. Impaired Dentition involves issues with teeth and oral health, which are not specific to Parkinson's disease complications.

4. What instruction should a client who is about to undergo pelvic ultrasonography be given by a healthcare provider?

• A. "Urinate prior to the test."?
• B. "Have someone drive you home."?
• C. "Do not drink after midnight."?
• D. "Drink plenty of water."?

Correct answer: D

Rationale: The correct instruction for a client about to undergo pelvic ultrasonography is to 'Drink plenty of water.' A full bladder is required to serve as a landmark to define pelvic organs during the procedure. It is important to ensure the bladder is adequately filled. 'Urinate prior to the test' (Choice A) would not be appropriate as a full bladder is needed for better visualization. 'Have someone drive you home' (Choice B) is unnecessary as no sedation is given during the procedure, so the client can drive home on their own. 'Do not drink after midnight' (Choice C) is unrelated and not necessary for a pelvic ultrasonography examination.

5. 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).
