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. Priorities designated as intermediate by the nurse are:

A. the nonemergency, non-life-threatening needs of the client.
B. those tasks that can be delegated to assistive personnel.
C. those tasks that can be performed at the end of the shift.
D. those tasks that can be performed at any time

Correct answer: A

Rationale: Priorities designated as intermediate by the nurse are those that are not urgent but still important, such as the nonemergency, non-life-threatening needs of the client. They do not impact the client's immediate physiological status but require attention. Intermediate priorities may need the skill level of an RN for completion and may have specific time requirements. Choices B, C, and D are incorrect because the priority being intermediate doesn't mean it can be delegated, done at a specific time, or done at any time; it simply indicates a non-urgent but necessary task for the client's well-being.

3. 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.

4. In what order should the LPN see the following clients? Use appropriate letters to match the correct order

A. A, D, B, C
B. C, B, D, A
C. D, C, B, A
D. B, C, A, D

Correct answer: B

Rationale: The correct order for the LPN to see the clients is C, B, D, A. It is crucial to prioritize client care based on the urgency of their conditions. The 53-year-old client with lower leg swelling complaining of sudden onset headache and blurry vision (Client C) should be seen first as they are at the highest risk for serious healthcare complications. Next, the LPN should attend to the 23-year-old client with a left arm fracture after an MVA complaining of significant pain in his arm (Client B). Following that, the LPN can address the 47-year-old client requesting more information regarding her surgery scheduled in three hours (Client D). Lastly, the LPN should attend to the 72-year-old client with pneumonia asking to order her dinner (Client A). This order ensures that the most critical needs are met first, followed by the less urgent ones. Choice A is incorrect as it places the 72-year-old client before the 23-year-old client with a painful arm. Choice B is incorrect as it prioritizes the 53-year-old client last. Choice D is incorrect as it does not address the urgency of the clients' conditions appropriately.

5. For which of the following conditions might blood be drawn to assess uric acid levels?

A. asthma
B. gout
C. diverticulitis
D. meningitis

Correct answer: B

Rationale: Uric acid levels are commonly assessed in patients with gout. Gout is a type of arthritis caused by the buildup of uric acid crystals in the joints, leading to inflammation and pain. Monitoring uric acid levels helps in diagnosing and managing gout. Asthma, diverticulitis, and meningitis are not conditions where blood tests for uric acid levels are typically necessary. Asthma is a respiratory condition, diverticulitis involves inflammation of the digestive tract, and meningitis is an infection of the meninges in the brain and spinal cord.
