A patient with chronic kidney disease (CKD) is prescribed erythropoietin. What is the primary action of this medication?
- A. Stimulate white blood cell production
- B. Increase platelet count
- C. Promote red blood cell production
- D. Enhance clotting factor production
Correct Answer: C
Rationale: The correct answer is C: Promote red blood cell production. Erythropoietin is a hormone that stimulates the production of red blood cells in the bone marrow. This is crucial for patients with CKD who often develop anemia due to decreased erythropoietin production.
A: Stimulating white blood cell production is the function of other medications, such as colony-stimulating factors, not erythropoietin.
B: Erythropoietin does not have an effect on platelet count.
D: Enhancing clotting factor production is not the primary action of erythropoietin.

When should the charge nurse intervene based on the observed behavior?
- A. Two staff members are overheard talking about a cure for AIDS outside a client's room.
- B. A hospital transporter is reading a client's history and physical while waiting for an elevator.
- C. A UAP tells a client, 'It's hard to quit drinking but Alcoholics Anonymous helped me.'
- D. Two visitors are discussing a hospitalized client's history of drug abuse in the visitor's lounge.
Correct Answer: B
Rationale: The correct answer is B because it violates patient confidentiality. Reading a client's history and physical in a public area breaches the client's privacy rights. The other choices do not directly compromise patient confidentiality. A involves discussing a cure for AIDS, which is not a breach of confidentiality. C involves sharing personal experiences with the client, and D involves discussing a client's history of drug abuse in a visitor's lounge, which may not be overheard by the client or staff directly involved in the client's care.
A patient with schizophrenia is prescribed olanzapine. What is an important side effect for the healthcare provider to monitor?
- A. Hypertension
- B. Weight gain
- C. Hypoglycemia
- D. Bradycardia
Correct Answer: B
Rationale: The correct answer is B: Weight gain. Olanzapine is known to cause metabolic side effects, including weight gain. This is important to monitor as it can lead to various health issues such as diabetes and cardiovascular problems. Hypertension (A), hypoglycemia (C), and bradycardia (D) are not commonly associated with olanzapine use, making them less likely side effects to monitor in this case.
What should be monitored to evaluate the effectiveness of enoxaparin in a patient with deep vein thrombosis (DVT)?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. International normalized ratio (INR)
- D. Platelet count
Correct Answer: C
Rationale: Rationale:
1. Enoxaparin is a low molecular weight heparin that primarily affects the intrinsic pathway of coagulation.
2. INR is used to monitor the effectiveness of anticoagulants affecting the intrinsic pathway.
3. Monitoring INR helps ensure the patient is within the therapeutic range to prevent clotting without excessive bleeding.
4. PT and PTT primarily evaluate the extrinsic and intrinsic pathways, respectively, not specific to enoxaparin.
5. Platelet count is not directly related to monitoring the effectiveness of enoxaparin in treating DVT.
A client is being discharged with a new prescription for enoxaparin (Lovenox). Which instruction should the nurse include?
- A. Administer the injection in your thigh.
- B. Do not expel the air bubble from the syringe before injection.
- C. Massage the injection site after administration.
- D. Alternate the injection site between the arms.
Correct Answer: B
Rationale: The correct answer is B because expelling the air bubble from the syringe before injection helps ensure accurate dosage delivery and prevents air from being injected into the patient. Administering the injection in the thigh (A) is incorrect as enoxaparin is typically given in the abdomen. Massaging the injection site (C) can cause bruising or hematoma formation. Alternating injection sites between arms (D) is not relevant as enoxaparin is usually given in the abdomen.
A patient with glaucoma is prescribed timolol eye drops. What is the primary action of this medication?
- A. Reduce intraocular pressure
- B. Dilate the pupils
- C. Constrict the pupils
- D. Enhance tear production
Correct Answer: A
Rationale: The correct answer is A: Reduce intraocular pressure. Timolol is a beta-blocker that works by decreasing the production of aqueous humor in the eye, thereby reducing intraocular pressure. This action helps to prevent damage to the optic nerve in patients with glaucoma. Choices B and C are incorrect because timolol does not affect pupil size. Choice D is incorrect because timolol does not enhance tear production; in fact, it may have a drying effect on the eyes.
