1. What is the most abundant positive ion in blood plasma?

Correct answer: C

Rationale: The correct answer is C: Sodium. Sodium (Na+) is the most abundant cation in the extracellular fluid, including blood plasma. It plays a crucial role in maintaining fluid balance, nerve function, and is essential for various physiological processes. Choice A, Potassium, is also an important ion in the body but is predominantly found intracellularly. Choice B, Calcium, is an essential mineral in the body but is not the most abundant positive ion in blood plasma. Choice D is incorrect as sodium is the primary positive ion in blood plasma, with a much higher concentration compared to potassium.

2. A nurse assesses a client who is prescribed a medication that inhibits aldosterone secretion and release. For which potential complications should the nurse assess? (Select all that apply.)

Correct answer: A

Rationale:

3. A nurse preparing to start an IV on a newly admitted patient teaches the patient about the procedure and begins to prepare the site. The nurse should always start by:

Correct answer: C

Rationale: Before preparing the skin, the nurse should ask the patient if they are allergic to latex or iodine, which are commonly used in IV therapy setup. This is crucial to prevent potential allergic reactions at the IV site or even life-threatening anaphylaxis. Leaving one hand ungloved (choice A) is not a recommended practice as both hands should be gloved for infection control. While preparing the skin with an iodine solution (choice B) is a step in the process, ensuring the patient's safety by checking for allergies comes first. Removing excessive hair at the selected site (choice D) is not necessary and can lead to skin irritation.

4. The nurse is assessing the patient for the presence of a Chvosteks sign. What electrolyte imbalance would a positive Chvosteks sign indicate?

Correct answer: C

Rationale:

5. A nurse in the medical-surgical unit has a newly admitted patient who is oliguric; the acute care nurse practitioner orders a fluid challenge of 100 to 200 mL of normal saline solution over 15 minutes. The nurse is aware this intervention will help:

Correct answer: C

Rationale: Administering a fluid challenge in oliguric patients helps to distinguish reduced renal blood flow from decreased renal function. This intervention aids in determining whether the oliguria is due to reduced renal blood flow (such as in fluid volume deficit or prerenal azotemia) or decreased renal function (such as in acute tubular necrosis). The response to this challenge can indicate the underlying cause. Choices A, B, and D are incorrect as they do not align with the purpose of a fluid challenge in oliguric patients.
