Question 1 of 5
A patient is started on a diuretic for antihypertensive therapy. The nurse expects that a drug in which class is likely to be used initially?
Correct Answer: C
Rationale: Thiazide diuretics are commonly used as first-line therapy for hypertension due to their effectiveness, safety profile, and affordability. They work by inhibiting sodium reabsorption in the distal convoluted tubule, leading to increased elimination of sodium and water, ultimately reducing blood volume and blood pressure. Thiazide diuretics are generally well-tolerated and have been shown to be effective in lowering blood pressure in patients with hypertension. Loop diuretics, such as furosemide, are more potent diuretics typically reserved for use in conditions where aggressive diuresis is needed, such as heart failure or renal disease. Osmotic diuretics, like mannitol, are primarily used for reducing intracranial pressure or preventing acute kidney injury. Potassium-sparing diuretics are often used in combination with other diuretics to prevent hypokalemia but are not typically used as
Question 2 of 5
A student nurse was asked by the nurse instructor to explain the procedure for the administration of erythromycin ointment to the eyes of the newborn. Which of the following statements made by the student indicates a need for further research?
Correct Answer: D
Rationale: After administering erythromycin ointment to the eyes of the newborn, there is no need to flush the eyes. The ointment is meant to be left in the eyes to provide protection against eye infections that can be acquired during birth. Flushing the eyes after instilling the ointment may reduce its effectiveness and is not part of the standard procedure. The ointment should be applied directly to the conjunctival sacs without rinsing or flushing the eyes.
Question 3 of 5
A nurse is doing an assessment data while completing an admission for a patient with a history of liver
Correct Answer: D
Rationale: Given the patient's history of liver transplant and current medications (prednisone and azathioprine), the nurse should pay close attention to an increased cholesterol level. Corticosteroids (such as prednisone) and immunosuppressants (such as azathioprine) can both contribute to dyslipidemia, leading to elevated cholesterol levels. Monitoring cholesterol levels is crucial in this patient population to assess cardiovascular risk and potentially adjust medications or lifestyle interventions accordingly. The other findings mentioned (soft non-tender lump in the shoulder, grade 1+ pitting edema in the feet, swollen and pinkish gums) may be important to note but do not directly relate to the patient's history of liver transplant and medication regimen.
Question 4 of 5
The student nurse asks the nursing instructor why he needs to take anatomy and physiology, as well as microbiology, when he only wants to learn about pharmacology. What is the best response by the instructor?
Correct Answer: C
Rationale: Anatomy, physiology, and microbiology underpin pharmacology, enabling nurses to grasp drug actions and patient responses, enhancing care through informed medication use. As an outgrowth oversimplifies their integration. Curriculum mandates explain requirements, not value. Understanding is key, but applying it to care-like knowing antibiotic targets or drug effects on organs-grounds pharmacology in practice, making it the best rationale.
Question 5 of 5
What is the therapeutic classification of phenytoin (Dilantin)
Correct Answer: C
Rationale: Phenytoin (Dilantin) belongs to the therapeutic class of anticonvulsants. Anticonvulsants are medications primarily used to treat and prevent seizures and are commonly prescribed for patients with epilepsy. Phenytoin works by stabilizing the electrical activity in the brain to prevent abnormal brain activity that leads to seizures. It is not classified as a mood stabilizer or bronchodilator; its main purpose is to control epileptic seizures.
