1. A client with Addison's disease is being admitted for a total hip arthroplasty. The client takes hydrocortisone. What is the nurse's priority action?
- A. Administering a supplemental dose of hydrocortisone
- B. Instructing the client about coughing and deep breathing
- C. Collecting additional information from the client about his history of Addison's disease
- D. Inserting an indwelling urinary catheter
Correct answer: A
Rationale: The priority action for a client with Addison's disease undergoing surgery who takes hydrocortisone is to administer a supplemental dose of hydrocortisone. Acute adrenal insufficiency (adrenal crisis) is a significant risk during surgery due to the stress placed on the body. Supplemental doses help prevent acute adrenal insufficiency and ensure the client's safety during the surgical procedure. Instructing the client about coughing and deep breathing is important post-operatively but not the priority before surgery. Collecting additional information about the client's history of Addison's disease is relevant but not the priority action before surgery. Inserting an indwelling urinary catheter is not the priority action in this scenario.
2. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
3. A healthcare professional is preparing to administer Filgrastim for the first time to a client who has just undergone a bone marrow transplant. Which of the following interventions is appropriate?
- A. Administer intravenously to prevent injury.
- B. Ensure that the medication is kept refrigerated until just prior to administration.
- C. Do not shake the vial; gently invert it to mix before withdrawing the dose.
- D. Discard the vial after removing one dose of the medication.
Correct answer: D
Rationale: When administering Filgrastim, only one dose should be withdrawn from the vial, and the vial should then be discarded to prevent any contamination or errors in dosing. It is crucial not to shake the vial but gently invert it to mix the medication before withdrawing the appropriate dose. Refrigeration is not required for Filgrastim; it should be stored at room temperature until just before administration. Choice A is incorrect because Filgrastim is typically administered subcutaneously, not intravenously. Choice B is incorrect as the medication should be stored at room temperature, not refrigerated, until administration. Choice C is incorrect as shaking the vial is not recommended for Filgrastim.
4. A healthcare professional is preparing to administer IV Dantrolene to a client who has developed Malignant Hyperthermia during surgery. Which of the following actions should the healthcare professional take?
- A. Dilute the medication with sterile water and administer it rapidly.
- B. Store the medication in a refrigerator until use.
- C. Administer the medication through a large-bore IV catheter.
- D. Administer the medication via an infusion pump over 60 minutes.
Correct answer: C
Rationale: Dantrolene should be administered through a large-bore IV catheter because it is highly irritating to tissues and can cause vein irritation or thrombophlebitis if administered through a small vein. Using a large-bore IV catheter helps to minimize the risk of tissue damage and ensures proper and safe administration of the medication in emergency situations like Malignant Hyperthermia. Choices A, B, and D are incorrect because diluting the medication with sterile water and administering it rapidly can lead to tissue damage, storing the medication in a refrigerator is not necessary, and administering the medication via an infusion pump over 60 minutes is not appropriate in emergency situations like Malignant Hyperthermia where rapid administration is crucial.
5. A client has a prescription for Alendronate. Which of the following instructions should the nurse include?
- A. Take this medication before bed.
- B. Take the medication with food.
- C. Sit upright for at least 30 minutes after taking the medication.
- D. Expect to have frequent headaches while on this medication.
Correct answer: C
Rationale: The correct instruction for a client prescribed Alendronate is to sit upright for at least 30 minutes after taking the medication. Alendronate can cause esophageal irritation, and maintaining an upright position helps prevent this adverse effect by reducing the risk of reflux of the medication into the esophagus. Choice A is incorrect because Alendronate should be taken in the morning, at least 30 minutes before the first food, beverage, or medication of the day with a full glass of plain water. Choice B is incorrect because Alendronate should not be taken with food. Choice D is incorrect because frequent headaches are not a common side effect of Alendronate.
