Correct Answer: A

Rationale: Ketamine is an anesthetic that induces dissociation and lack of awareness in a client. It can be used before general anesthesia or during short procedures for sedation. Ketamine may lead to side effects such as delirium, hallucinations, hypertension, and respiratory depression. Therefore, the nurse should monitor the client for delirium, as it is a potential side effect associated with ketamine use. Muscle rigidity, hypotension, and pinpoint rash are not typically attributed to ketamine administration and are less likely to occur in this scenario.

Correct Answer: C

Rationale: Chest pain, dyspnea, tachypnea, mild fever, and rales or crackles on auscultation in a client who had surgery 2 days ago may be indicative of a pulmonary embolism. The nurse should administer oxygen to address his breathing and assist him to a comfortable position to facilitate better oxygenation before contacting the physician. Placing the client in the Trendelenburg position is not recommended in this situation as it may worsen a potential pulmonary embolism by increasing venous return. Contacting the physician for antibiotics is not the priority as the immediate concern is addressing the breathing difficulty. Decreasing the IV rate is not indicated in this situation where the client is experiencing respiratory distress and needs oxygen therapy.

Correct Answer: C

Rationale: When caring for a client with a broken femur in a traction splint, turning the client to a side-lying position is not recommended. This client is at risk of skin breakdown and complications due to the injury, making it important to prevent unnecessary movement that may increase the risk of injury or discomfort. Palpating the temperature of both feet helps in assessing circulation, evaluating pulses bilaterally ensures perfusion to the extremities, and relieving heel pressure by placing a pillow under the foot helps in reducing pressure points and preventing complications like pressure ulcers. Therefore, the correct answer is turning the client to a side-lying position as it is not a recommended intervention in this scenario.

Correct Answer: A

Rationale: A client in restraints is at an increased risk of aspiration of stomach contents. When a client is restrained, they may be unable to effectively move or turn their body if they begin to vomit, which can lead to aspiration. This lack of mobility can hinder their ability to protect their airway. On the other hand, a scaphoid abdomen, which is sunken or hollowed, is not a direct risk factor for aspiration. Additionally, lying prone, facing downward, does not necessarily increase the risk of aspiration, as aspiration is more likely when lying supine (facing upward). Therefore, the correct answer is that a client is in restraints.

Correct Answer: D

Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (Choice B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (Choice C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (Choice A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.
