1. The nurse is caring for a postthyroidectomy patient at risk for hypocalcemia. What action should the nurse take when assessing for hypocalcemia?

Correct answer: D

Rationale: Muscle twitching and numbness or tingling of the lips, fingers, and toes are signs of hyperirritability of the nervous system due to hypocalcemia. The other options describe complications the nurse should also be observing for; however, tetany and neurologic alterations are primary indications of hypocalcemia. Monitoring for an elevated thyroid-stimulating hormone (choice A) is not relevant in assessing for hypocalcemia. Observing for swelling of the neck, tracheal deviation, and severe pain (choice B) are more related to airway compromise. Evaluating the quality of the patient's voice postoperatively (choice C) is important but not a primary sign of hypocalcemia.

2. The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?

Correct answer: B

Rationale: When selecting a site for IV insertion on the hand or arm, it is important to consider the potential effects on the patient's mobility. The chosen site should not interfere with the patient's movement. Instructing the patient to hold his arm in a dependent position helps increase blood flow, aiding in vein visualization and insertion. It is advisable to choose a site with minimal hair if possible for better adhesion of the dressing. Removing the tourniquet after 2 minutes is recommended to prevent complications like hemoconcentration and potential vein damage. Therefore, option B is the correct choice as it aligns with best practices for IV insertion.

3. A nurse assesses a client who is prescribed furosemide (Lasix) for hypertension. For which acid-base imbalance should the nurse assess to prevent complications of this therapy?

Correct answer: D

Rationale:

4. Third spacing occurs when fluid moves out of the intravascular space but not into the intracellular space. Based on this fluid shift, the nurse will expect the patient to demonstrate:

Correct answer: D

Rationale: In the scenario of third-spacing fluid shift, where fluid moves out of the intravascular space but not into the intracellular space, the patient is expected to demonstrate hypovolemia. Hypertension (Choice A) is unlikely as hypovolemia typically leads to decreased blood pressure. Bradycardia (Choice B) is not a common manifestation of hypovolemia, as the body often tries to compensate by increasing heart rate. Hypervolemia (Choice C) indicates an excess of fluid, which is the opposite of what occurs in third spacing.

5. Which of the following is not considered an extracellular fluid?

Correct answer: D

Rationale: The correct answer is D. Cerebrospinal fluid and the humors of the eye are not considered extracellular fluids. Extracellular fluids are fluids found outside the cells, such as interstitial fluid and lymph. Cerebrospinal fluid is found within the central nervous system, while the humors of the eye (aqueous humor and vitreous humor) are located within the eyeball, making them distinct from extracellular fluids.
