Question 2 of 4
The nurse is caring for a young patient with a closed head injury who has an intracranial pressure of 35 (normal <20) and serum osmolality of 330 mOsm/kg. The nurse would anticipate which action?
Correct Answer: B
Rationale: Mannitol is an osmotic diuretic used to reduce intracranial pressure (ICP) by drawing fluid out of the brain tissue. However, it should be used cautiously in patients with elevated serum osmolality, as it can exacerbate hyperosmolality and lead to renal failure or other complications. In this case, the patient's serum osmolality is already high (330 mOsm/kg), so mannitol should be withheld, and other measures to reduce ICP, such as elevating the head of the bed, maintaining proper oxygenation, and avoiding hypercapnia, should be prioritized. Sodium nitroprusside (C) is used for hypertension, not ICP, and taking no action (D) is inappropriate given the elevated ICP.
Question 3 of 4
The nurse is teaching a patient about taking aspirin. Which are important points to include? (Select all that apply.)
Correct Answer: D
Rationale: Aspirin is an antiplatelet agent that can increase the risk of bleeding, especially when combined with alcohol or during invasive procedures like dental work or surgery. Patients should avoid alcohol to reduce the risk of gastrointestinal bleeding. Additionally, informing healthcare providers about aspirin use is crucial to prevent excessive bleeding during procedures. Taking aspirin on an empty stomach is not recommended, as it can increase the risk of gastric irritation. Therefore, the correct teaching points are to avoid alcohol, inform the dentist, and inform the surgeon about aspirin use.
Question 4 of 4
A contraindication for topical corticosteroid usage in a male patient with atopic dermatitis (eczema) is:
Correct Answer: B
Rationale: Topical corticosteroids can exacerbate viral infections, such as herpes simplex, by suppressing the immune response. They are contraindicated in the presence of viral infections to prevent worsening of the condition. Bacterial, parasitic, and spirochete infections are not absolute contraindications, although caution is advised.
