ATI PN Pharmacology 2020 Exam 2 Questions
Extract:
Question 1 of 5
A nurse is administering spironolactone at 0800 to a client who has heart failure. The nurse should monitor the client for which of the following adverse effects?
Correct Answer: B
Rationale: Spironolactone is not associated with hypophosphatemia. Spironolactone is a potassium-sparing diuretic, and hyperkalemia is a potential adverse effect due to reduced potassium excretion. Spironolactone is not associated with hypocalcemia. Spironolactone is not associated with hypernatremia; rather, it promotes sodium excretion.
Question 2 of 5
A nurse is preparing to mix NPH insulin and regular insulin for administration. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The nurse should inject air into the NPH insulin vial first, then into the regular insulin vial, then withdraw the regular insulin first, followed by the NPH insulin. The nurse should inject air into each vial before withdrawing the insulin to prevent contamination and maintain the correct dosage. Insulin should be drawn up with an insulin syringe, not a tuberculin syringe. Shaking insulin vials is not recommended as it can cause denaturation of the insulin molecules.
Question 3 of 5
A nurse is caring for a client who has been taking epoetin alfa for 3 months. Which of the following laboratory tests should the nurse monitor to determine the effectiveness of the medication?
Correct Answer: C
Rationale: T4 is a thyroid hormone, and monitoring it is not relevant for assessing the effectiveness of epoetin alfa. Troponin is a marker for cardiac injury and is not relevant for assessing the effectiveness of epoetin alfa. Epoetin alfa stimulates the production of red blood cells, so monitoring hemoglobin levels is crucial to assess its effectiveness. AST is a liver enzyme and is not relevant for assessing the effectiveness of epoetin alfa.
Question 4 of 5
A nurse is preparing to administer enoxaparin subcutaneously to a client using a prefilled syringe. The nurse should plan to use which of the following techniques when administering this medication?
Correct Answer: B
Rationale: The air bubble helps to ensure that the entire dose of medication is delivered and prevents bleeding from the injection site. The nurse should plan to inject enoxaparin subcutaneously into abdominal tissue using a prefilled syringe without expelling the air bubble or aspirating prior to injecting the medication. Aspiration is not recommended because it may cause hematoma formation. Massaging the site is generally not recommended after enoxaparin injections to avoid bruising or hematoma formation.
Question 5 of 5
A nurse is reviewing data for a client who receives clonidine daily. Which of the following findings indicates the nurse should withhold the next dose?
Correct Answer: C
Rationale: Clonidine primarily affects blood pressure and not heart rate. Clonidine does not directly affect urine output. Clonidine is an antihypertensive medication, and a low blood pressure reading indicates the need to withhold the next dose. Clonidine does not typically affect blood glucose levels.
