1. A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?

Correct answer: A

Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.' Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2. Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis. Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.

2. A client has been administered ketamine by a physician in preparation for general anesthesia. Which of the following side effects should the nurse monitor for in this client?

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.

3. How can the dangers associated with wandering in Alzheimer's disease patients be prevented?

Correct answer: D

Rationale: The correct answer is 'All of the above.' Bed alarms, chair alarms, and door alarms are all effective measures to prevent the dangers associated with wandering in Alzheimer's disease patients. These alarms can alert caregivers when a patient tries to leave a designated area, helping to keep them safe. It is crucial to respond promptly to these alarms to ensure the patient's safety. Choices A, B, and C are incorrect individually as each type of alarm plays a vital role in a comprehensive wandering prevention strategy.

4. While caring for a client in labor, a nurse attaches an electronic fetal monitor to the client's abdomen to assess the baby's heart rate. The nurse observes that the baby's heart rate slows down during each contraction and does not return to normal limits until after the contraction is complete. What type of fetal heart rate change does this pattern describe?

Correct answer: B

Rationale: Late decelerations are characterized by the baby's heart rate declining in utero during contractions. The heart rate drops below baseline and stays low until after the contraction ends. Late decelerations are concerning as they indicate uteroplacental insufficiency, which can compromise fetal oxygenation. This pattern is a non-reassuring sign and requires immediate intervention. Variable decelerations are typically abrupt decreases in heart rate, often associated with cord compression. Early decelerations, on the other hand, mirror the contractions and are considered benign, resulting from fetal head compression. Accelerations are reassuring signs of fetal well-being, indicating a responsive and healthy fetal nervous system.

5. When should discharge training and planning begin for a 65-year-old man admitted to the hospital for spinal stenosis surgery?

Correct answer: B

Rationale: Discharge training and planning should begin upon admission for a patient undergoing spinal stenosis surgery. It is crucial to initiate this process early to ensure a smooth transition from hospital care to home or a rehabilitation facility. Starting discharge planning upon admission allows for comprehensive involvement of the patient, family, and healthcare team, which can reduce the risk of readmission, optimize recovery, ensure proper medication management, and adequately prepare caregivers. Therefore, option B, 'Upon admission,' is the correct answer. Options A, C, and D are incorrect because waiting until after surgery, within 48 hours of discharge, or during preoperative discussion would not provide sufficient time for effective discharge planning and education.
