Correct Answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.

Correct Answer: B

Rationale: Repositioning the client onto her left side is the appropriate intervention when late decelerations are noted on the monitor tracing. This action helps increase uteroplacental blood flow by relieving pressure on the vena cava and aorta, improving fetal oxygenation. Administering oxygen via nasal cannula may be indicated for variable decelerations, not late decelerations. Administering an amnioinfusion is not the primary intervention for late decelerations. Providing reassurance to the client is important but addressing the underlying cause of late decelerations takes precedence.

Correct Answer: D

Rationale: The correct answer is D, dry mouth. Dry mouth is a common side effect of radiation therapy due to damage to the salivary glands. It is essential for the nurse to monitor for this condition as it can lead to oral health issues and discomfort. Fatigue (choice A) is a common side effect of radiation therapy, but in this case, dry mouth is a more specific side effect to monitor for. Hair loss (choice B) is more commonly associated with chemotherapy rather than radiation therapy. Nausea (choice C) is also a common side effect of radiation therapy, but dry mouth is a more direct effect of the treatment that the nurse should focus on monitoring.

Correct Answer: B

Rationale: The best position for a patient experiencing shortness of breath is the Semi-Fowler's position. This position promotes lung expansion and improves oxygenation by allowing the chest to expand more fully. The Supine position (lying flat on the back) may worsen breathing difficulties by reducing lung capacity. The Trendelenburg position (feet elevated higher than the head) is not recommended for patients with shortness of breath as it can increase pressure on the diaphragm and compromise breathing. The Prone position (lying face down) is also not suitable for patients experiencing shortness of breath as it may further restrict breathing.

Correct Answer: C

Rationale: The correct answer is a low-sodium diet. Patients with chronic kidney disease are often advised to follow a low-sodium diet to help manage fluid retention. Excessive sodium intake can lead to fluid buildup in the body, causing complications for individuals with kidney issues. Choices A and B are incorrect because while protein intake may need to be monitored in kidney disease, the primary focus is typically on sodium restriction. Choice D is incorrect as a high-sodium diet would exacerbate fluid retention in patients with chronic kidney disease.
