A nurse is caring for a client who is receiving radiation therapy. Which of the following side effects should the nurse monitor for?

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: A

Rationale: The correct answer is to administer oxygen. Post-surgery, confusion in a patient could be due to hypoxia, a condition where the body is deprived of an adequate oxygen supply. Administering oxygen helps address hypoxia promptly, improving oxygen levels in the body and potentially resolving the confusion. Repositioning the patient, checking oxygen saturation, and performing a neurological exam may be important interventions but addressing hypoxia with oxygen administration takes precedence as the priority action.

Correct Answer: C

Rationale: Auscultating crackles in the lung bases indicates fluid in the lungs, which can be a sign of aspiration pneumonia or pulmonary edema and requires immediate intervention to prevent respiratory distress. Aspirating 100 mL of gastric residual is within the acceptable range and does not require immediate intervention. A gastric pH of 4 is normal for gastric contents. Checking residual every 6 hours is a routine nursing intervention and does not indicate an urgent issue like pulmonary complications.

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: C

Rationale: The correct answer is C because the client stating they should only take the inhaler when feeling short of breath indicates a need for further teaching. Clients with asthma should use their inhaler as prescribed, not just when short of breath. Choices A, B, and D demonstrate good asthma management practices. Choice A indicates understanding of using the albuterol inhaler before exercise to prevent exercise-induced symptoms. Choice B mentions the importance of not overusing the inhaler, which can indicate poor asthma control. Choice D shows awareness of rinsing the mouth after using a corticosteroid inhaler to prevent oral thrush.

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 to monitor digoxin levels in a patient on digoxin. Digoxin is a medication commonly used to treat heart conditions, and monitoring its levels in the blood is crucial to ensure that the patient is within the therapeutic range and to prevent toxicity. Monitoring potassium levels (Choice A) is important due to the potential of digoxin-induced hypokalemia, but the primary focus should be on monitoring digoxin levels. Monitoring calcium levels (Choice B) and sodium levels (Choice D) are not directly related to digoxin therapy and are not the primary lab values of concern when administering digoxin.

Correct Answer: A

Rationale: Administering diuretics is the best method to manage fluid overload in a patient with heart failure. Diuretics help to remove excess fluid from the body by increasing urine output, thus reducing the fluid volume in the bloodstream and tissues. Providing oral fluids (choice B) or increasing fluid intake (choice C) would exacerbate the fluid overload rather than managing it. Chest physiotherapy (choice D) is not indicated for managing fluid overload in heart failure; it is more commonly used for conditions affecting the lungs or airways.

Correct Answer: D

Rationale: The correct action for a client 1 day postoperative following a total knee arthroplasty is to apply ice packs to the affected knee. Ice packs help reduce swelling and pain in such clients. Administering aspirin is contraindicated due to the risk of bleeding postoperatively. Keeping the affected leg in a dependent position can impair circulation and increase the risk of complications. Flexing the affected knee for extended periods can strain the surgical site and hinder the healing process.
