Correct Answer: B

Rationale: Shoulder presentation is a contraindication for oxytocin because it can increase the risk of complications during labor, such as shoulder dystocia. Diabetes mellitus (Choice A) is not a contraindication for the use of oxytocin. Postterm with oligohydramnios (Choice C) and chorioamnionitis (Choice D) may actually necessitate the use of oxytocin to induce or augment labor for the well-being of the mother and baby.

Correct Answer: C

Rationale: The correct answer is to check the oxygen level regularly using a pulse oximeter. This instruction is crucial as it ensures safe and adequate oxygenation for the client. Option A is incorrect as oxygen should not be stored in a storage room but in a well-ventilated area. Option B is not ideal as oxygen should be left on unless otherwise specified by a healthcare provider. Option D is also important but not directly related to the primary instruction of monitoring oxygen levels.

Correct Answer: D

Rationale: The correct answer is D. Dyspnea in a client with COPD receiving oxygen should be reported as it may indicate worsening respiratory status. Oxygen saturation of 95% is within the expected range for a client receiving oxygen therapy and does not require immediate reporting. A productive cough with clear sputum is a common symptom in clients with COPD and does not necessarily warrant urgent reporting. A respiratory rate of 22/min is also within normal limits and does not raise immediate concerns in this scenario.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid crowds to reduce the risk of infection.' Clients receiving chemotherapy are immunocompromised, so avoiding crowds can help decrease the likelihood of exposure to infections. Wearing a mask when gardening (choice A) is important but not directly related to infection prevention in the context of chemotherapy. Taking a daily vitamin (choice C) may be beneficial for overall health but is not specifically focused on infection prevention. Increasing intake of high-protein foods (choice D) is essential for nutrition but does not directly address infection prevention.

Correct Answer: B

Rationale: The correct action the nurse should include in the plan of care when caring for a client receiving hemodialysis is to check the vascular access site for bleeding after dialysis. This is crucial to monitor for any signs of bleeding or complications at the access site. Withholding all medications until after dialysis (Choice A) is not necessary unless specified for certain medications. Rehydrating with dextrose 5% in water for hypotension (Choice C) is not appropriate for addressing hypotension related to hemodialysis. Giving an antibiotic 30 minutes before dialysis (Choice D) is not typically indicated unless there is a specific medical indication for prophylactic antibiotic use.
