1. What should a patient avoid while taking Angiotensin-converting enzymes?
- A. Salt substitutes
- B. Foods high in potassium
- C. Foods high in sodium
- D. All of the above
Correct answer: A
Rationale: Patients taking Angiotensin-converting enzyme (ACE) inhibitors should avoid salt substitutes because they can contain potassium chloride, which may lead to hyperkalemia. It is important to restrict potassium-rich foods while on ACE inhibitors, but the primary concern with salt substitutes is their potassium content.
2. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?
- A. These medications work by blocking HIV entry into cells.
- B. These medications work by weakening the cell wall of the HIV virus.
- C. These medications work by inhibiting enzymes to prevent HIV replication.
- D. These medications work by preventing protein synthesis within the HIV cell.
Correct answer: C
Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.
3. A healthcare provider is preparing to administer a transfusion of a unit of packed red blood cells (PRBCs) for a client who has severe anemia. Which of the following interventions will prevent an acute hemolytic reaction?
- A. Ensure that the client has a patent IV line before obtaining the blood product from the refrigerator.
- B. Obtain help from another healthcare provider to confirm the correct client and blood product.
- C. Take a complete set of vital signs before beginning the transfusion and periodically during the transfusion.
- D. Stay with the client for the first 15 to 30 minutes of the transfusion.
Correct answer: B
Rationale: The correct answer is to obtain help from another healthcare provider to confirm the correct client and blood product. This action is crucial in preventing an acute hemolytic reaction, which is caused by ABO or Rh incompatibility. Verifying the correct client and blood product before the transfusion ensures that there are no errors in identification, reducing the risk of a potentially life-threatening reaction. Choices A, C, and D are important aspects of transfusion safety but are not directly related to preventing acute hemolytic reactions. Ensuring a patent IV line, monitoring vital signs, and staying with the client are all essential during transfusion but do not specifically address the risk of ABO or Rh incompatibility reactions.
4. A client with migraine headaches is starting prophylaxis therapy with Propranolol. Which finding in the client's history should the nurse report to the provider?
- A. The client had a prior myocardial infarction.
- B. The client takes warfarin for atrial fibrillation.
- C. The client takes an SSRI for depression.
- D. An ECG indicates a first-degree heart block.
Correct answer: D
Rationale: Propranolol is contraindicated in clients with first-degree heart block due to its negative inotropic and chronotropic effects. The nurse should report this finding to the provider to consider an alternative therapy to prevent potential worsening of cardiac conduction abnormalities. Choices A, B, and C are not directly contraindications to Propranolol therapy for migraine headaches and do not pose immediate risks that would require reporting to the provider.
5. What is the antidote for Heparin?
- A. Atropine
- B. Protamine sulfate
- C. Calcium carbonate
- D. Ferrous sulfate
Correct answer: B
Rationale: Protamine sulfate is the specific antidote used to reverse the effects of Heparin by binding to heparin and neutralizing its anticoagulant properties. It is crucial to administer Protamine sulfate promptly in cases of Heparin overdose or when immediate reversal of Heparin's effects is required to prevent bleeding complications. Atropine is not the antidote for Heparin; it is commonly used for treating bradycardia. Calcium carbonate is used to treat conditions like acid indigestion, heartburn, or calcium deficiency. Ferrous sulfate is a form of iron supplement used to treat or prevent iron deficiency anemia. None of these alternatives are antidotes for Heparin.
