Which of the following interventions should the nurse implement for a client with dementia who is at risk of falling?

Correct Answer: D

Rationale: The correct intervention for a client with dementia at risk of falling is to use a bed exit alarm to notify staff of attempts to leave the bed. This intervention helps in preventing falls by alerting the staff when the client tries to get out of bed. Keeping the bed in the lowest position (Choice A) may not prevent falls and could make it challenging for staff to provide care. Raising all four side rails (Choice B) can be a restraint and is not recommended as it may lead to entrapment or other risks. Assisting with ambulation every 2 hours (Choice C) may not be feasible or effective in preventing falls, as the client may attempt to get out of bed at any time.

Correct Answer: B

Rationale: Performing a wound culture before administering antibiotics is crucial when managing a client with a wound infection. This step helps identify the specific pathogens causing the infection, allowing for the prescription of the most effective antibiotics. Changing the wound dressing every 24 hours (Choice A) is important for wound care but not the priority when an infection is present. Cleansing the wound with alcohol-based solutions (Choice C) can be too harsh and may delay wound healing. Applying a wet-to-dry dressing (Choice D) is not recommended for infected wounds as it can cause trauma to the wound bed during dressing changes.

Correct Answer: A

Rationale: The correct answer is to administer insulin. In hyperglycemia, there is an excess of glucose in the blood, which needs to be lowered. Insulin is the primary medication used to lower blood glucose levels by facilitating the uptake of glucose into cells. Encouraging the client to exercise may further increase blood glucose levels due to the release of stress hormones, so it is not the priority. While staying hydrated is important, it will not directly address the high blood glucose levels seen in hyperglycemia. Glucagon is used to treat severe hypoglycemia, not hyperglycemia, so it is not the priority in this situation.

Correct Answer: D

Rationale: The correct action the nurse should take is to gently close the client's eyelids. This is a respectful and common practice in postmortem care before allowing the family to view the body. Applying moisturizing lotion to the skin is unnecessary and may not be appropriate at this time. Turning off the lights might not be necessary and could impact the viewing environment for the family. While removing all jewelry is generally a good practice, it is not as crucial as gently closing the client's eyelids for postmortem care.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Hypokalemia is an adverse effect of digoxin. Digoxin can cause hypokalemia, which increases the risk of toxicity. Monitoring potassium levels is crucial when a client is taking digoxin. Choices B, C, and D are incorrect as hypernatremia, hypertension, and tachycardia are not directly associated with digoxin use.

Correct Answer: A

Rationale: When assessing a patient with a suspected infection, it is crucial to monitor temperature and check for elevated white blood cells. Elevated temperature indicates a potential infection, and increased white blood cells are a sign of inflammation and the body's response to an infection. Monitoring blood pressure (choice B) and checking for fever (choice B) are not as specific indicators of infection as monitoring temperature and white blood cell count. Assessing changes in mental status and monitoring urine output (choice C) are important aspects of patient assessment but may not directly indicate a suspected infection. Administering antibiotics (choice D) should only be done after a confirmed diagnosis of a bacterial infection, as unnecessary antibiotic use can lead to antibiotic resistance and other adverse effects.

Correct Answer: D

Rationale: The correct answer is 'Muscle weakness.' Hypokalemia is characterized by low potassium levels, which can lead to muscle weakness due to impaired muscle function. Choices A, B, and C are incorrect findings associated with other medical conditions and not typically expected in hypokalemia. Muscle stiffness is more commonly associated with conditions like tetany or muscle cramps, bradycardia is more commonly associated with issues like heart block or hypothyroidism, and hyperreflexia is more commonly seen in conditions like hyperthyroidism or spinal cord injuries.

Correct Answer: A

Rationale: The correct answer is A: Level of consciousness. Following a TURP procedure, monitoring the client's level of consciousness is crucial as it can indicate potential postoperative complications such as hemorrhage or shock. Skin turgor (choice B) is more related to hydration status, deep-tendon reflexes (choice C) are not the priority post-TURP, and bowel sounds (choice D) are important but not the priority in this situation.

Correct Answer: A

Rationale: The appropriate action for a healthcare professional when administering a blood transfusion is to verify the patient's identity. This step is essential to ensure that the correct blood product is given to the right patient, preventing any errors or adverse reactions. While monitoring vital signs and staying with the patient during the initial phase of the transfusion are also important steps, the primary action of verifying the patient's identity takes precedence to uphold patient safety and prevent any potential harm.
