A patient is being treated for dehydration. Which lab result would support the diagnosis?

Correct Answer: D

Rationale: Elevated BUN levels are a characteristic finding in dehydration due to reduced kidney perfusion and increased reabsorption of urea. Hemoglobin levels might be elevated in conditions like polycythemia vera, not directly related to dehydration. A low sodium level could be seen in conditions like hyponatremia. A high white blood cell count is more indicative of infection or inflammation rather than dehydration.

Correct Answer: C

Rationale: The correct action the nurse should add to the client's plan of care is to wrap blankets around side rails. This helps prevent injury during seizures by providing a cushioned surface against the hard rails. Applying restraints (Choice A) is not recommended as it can cause harm during a seizure. Using soft wristbands (Choice B) may not provide adequate protection against injury. Administering sedatives (Choice D) is not typically indicated for managing tonic-clonic seizures as they require specific anti-seizure medications.

Correct Answer: B

Rationale: The correct answer is to inject enoxaparin subcutaneously at a 45-degree angle. This angle helps ensure proper delivery of the medication into the subcutaneous tissue. Option A (Inject at a 90-degree angle) is incorrect because subcutaneous injections are usually given at a shallower angle. Option C (Massage the injection site after administering) is incorrect as massaging the site can cause bruising and should generally be avoided. Option D (Use a longer needle) is incorrect as using a longer needle is unnecessary and may increase the risk of injecting the medication too deeply.

Correct Answer: B

Rationale: The correct answer is B: Driving a car. Driving a car can be physically and emotionally taxing, increasing the risk of complications soon after a myocardial infarction. It requires quick reflexes and decision-making abilities, which may be impaired during the recovery period. Swimming in a pool, light housework, and walking on flat ground are generally safe and beneficial activities for clients following a myocardial infarction as they promote circulation, muscle strength, and overall well-being.

Correct Answer: C

Rationale: The correct answer is C because white rice is a low-fiber food suitable for a low-fiber diet, making it an appropriate choice. Choices A, B, and D are incorrect because fresh pear, refried beans, and bran cereal are high-fiber foods and not suitable for a low-fiber diet.

Correct Answer: B

Rationale: The correct nursing interventions for a patient with pneumonia include monitoring lung sounds and respiratory rate to assess the effectiveness of treatment and the patient's respiratory status. Providing fluids and rest (Choice A) can be supportive measures but are not specific nursing interventions for pneumonia. Encouraging coughing and deep breathing exercises (Choice C) can be helpful for airway clearance but may not be appropriate for all patients with pneumonia. Administering antibiotics and providing oxygen therapy (Choice D) are medical interventions rather than nursing interventions.

Correct Answer: A

Rationale: Administering oral antibiotics is within the scope of practice for an LPN and can be safely delegated. LPNs are trained to administer medications, including oral ones. Performing an admission assessment (Choice B) involves critical thinking and comprehensive evaluation, typically done by registered nurses. Creating new teaching material (Choice C) requires specialized knowledge and is usually the responsibility of a nurse with additional training in education. Administering IV conscious sedation (Choice D) is a high-risk task that requires advanced skills and should be performed by a registered nurse or higher-level provider.

Correct Answer: C

Rationale: The correct answer is C because avoiding alcohol before bedtime can help promote better sleep. Choice A is incorrect as vigorous exercise close to bedtime can actually hinder sleep. Choice B is also incorrect as consuming beverages with caffeine or sugar close to bedtime can disrupt sleep. Choice D, while a good practice, does not directly address the issue of avoiding alcohol before bedtime to improve sleep quality.

Correct Answer: C

Rationale: The correct answer is C. Somatic symptom disorder is characterized by individuals having excessive preoccupation with physical symptoms that may or may not have an identifiable medical cause. Choice A is incorrect because the sudden onset of symptoms due to stress is more indicative of acute stress reaction. Choice B is incorrect as it describes physical manifestations related to known medical conditions, not somatic symptom disorder. Choice D is incorrect as it relates to health anxiety or illness anxiety disorder, where individuals avoid seeking medical care due to fear of receiving a diagnosis.
