When assessing a male client, the nurse finds that he is fatigued and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?

Correct Answer: D

Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.

Correct Answer: B

Rationale: The best nursing action in response to a terminally ill client stating their agnostic beliefs is to document the client's spiritual assessment. By documenting this information, the healthcare team can ensure that the client's beliefs are acknowledged and respected in their care plan. Providing information about the chapel's hours or inviting the client to a healing service may not align with the client's beliefs and preferences. Offering to contact a spiritual advisor of the client's choice may not be necessary if the client has clearly stated their agnostic beliefs, as they may not wish to engage in spiritual counseling.

Correct Answer: D

Rationale: Choice D is the correct response. The body's receptors adapt to the heat over time, which can explain why the client no longer perceives the warmth from the heating pad. This phenomenon is known as thermal adaptation. Choices A, B, and C are incorrect. Choice A is inaccurate because the client not feeling the warmth does not necessarily mean they have derived the maximum benefit. Choice B incorrectly states that blood vessels dilating remove heat, which is not accurate. Choice C suggests increasing the temperature when the pad no longer feels warm, which could potentially lead to burns or discomfort for the client.

Correct Answer: C

Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.

Correct Answer: D

Rationale: Encouraging additional oral intake of juices and water is the appropriate intervention in this scenario. Dark amber urine can indicate concentrated urine due to dehydration or other factors. By encouraging more fluids, the LPN/LVN can help dilute the urine, reducing the concentration of pigments causing the dark color. Providing additional coffee (Choice A) would not necessarily increase hydration and could potentially have a diuretic effect. Exchanging grape juice for cranberry juice (Choice B) does not address the core issue of hydration. Bringing additional fruit (Choice C) may provide some fluid, but encouraging specific fluids like juices and water would be more effective in diluting the urine.
