Correct Answer: B

Rationale: Tingling and numbness in the hands can indicate hypocalcemia, a common complication following a thyroidectomy. Hypocalcemia requires immediate intervention to prevent severe complications like tetany and seizures. Calcium gluconate is the drug of choice for rapidly raising serum calcium levels in hypocalcemic patients. Sodium bicarbonate is not indicated for treating hypocalcemia or related symptoms. Potassium chloride is used to correct potassium imbalances, not calcium. Magnesium sulfate is not the appropriate treatment for hypocalcemia; it is commonly used for conditions like preeclampsia or eclampsia.

Correct Answer: B

Rationale: To prevent dislocation of the prosthesis after hip replacement surgery, it is essential to avoid bending the hip more than 90 degrees. This precaution helps maintain the stability of the hip joint and reduces the risk of prosthesis dislocation. Crossing legs at the knees (Choice A) can increase pressure on the hip joint, leading to instability. Sitting with legs elevated (Choice C) and avoiding placing a pillow under the knees (Choice D) do not directly address the risk of prosthesis dislocation.

Correct Answer: C

Rationale: The correct answer is C because the patient's voluntary or involuntary status should not impact the nurse's actions when using restraints. The use of restraints should be based on the patient's behavior and the need to ensure their safety and the safety of others. Choices A, B, and D are important factors that should influence the nurse's actions. The institution's restraints/seclusion policies provide guidelines on the appropriate use of restraints, the patient's competence helps determine their understanding and ability to control their behavior, and the patient's nursing care plan guides the overall care provided, including the use of restraints if necessary.

Correct Answer: C

Rationale: Placing a pillow between the legs is essential post-total hip arthroplasty to prevent adduction of the hip joint, reducing the risk of dislocation. Choices A, B, and D are incorrect. Using a walker while walking is encouraged for support and stability. Keeping the hip flexed at 90° while sitting can increase the risk of hip dislocation. Crossing legs at the ankles when sitting may also lead to hip dislocation.

Correct Answer: B

Rationale: In this scenario, with the client's cervix dilated to only 1 cm and an unengaged presenting part, the priority action is to apply the external fetal monitor. This allows for continuous monitoring of the fetal heart rate during early labor, which is crucial for assessing fetal well-being. Encouraging the client to bear down is not appropriate at 1 cm dilation, as it may not be effective and can lead to exhaustion. Providing the client with fluids or administering IV fluids may be necessary for hydration, but the immediate concern is monitoring fetal well-being.
