A nurse receives a unit of packed RBCs from a blood bank and notes that the time is 1130. The nurse should begin the infusion at which of the following times?
- A. As soon as the nurse can prepare the client and the administration set
- B. One hour after receiving the blood
- C. Two hours after receiving the blood
- D. Immediately after lunch break
Correct Answer: A
Rationale: The correct answer is A. The nurse should begin the infusion as soon as possible after receiving the packed RBCs to prevent bacterial growth and ensure the blood's optimal efficacy. Delaying the infusion could increase the risk of contamination. Choice B (one hour after receiving the blood) is incorrect because it unnecessarily delays the infusion. Choice C (two hours after receiving the blood) is also incorrect as it further prolongs the time before starting the infusion. Choice D (immediately after lunch break) is incorrect as it does not prioritize the immediate need to administer the blood. Starting the infusion promptly is crucial to prevent any adverse reactions or complications for the patient.

A nurse cares for a client on ethambutol therapy for tuberculosis. What should be monitored?
- A. Hearing loss
- B. Visual acuity
- C. Liver function
- D. Blood glucose
Correct Answer: B
Rationale: The correct answer is B: Visual acuity. Ethambutol can cause optic neuritis, leading to visual disturbances. Monitoring visual acuity is crucial to detect any changes early.
Incorrect choices:
A: Hearing loss is associated with other medications for TB, not ethambutol.
C: Liver function is not typically affected by ethambutol.
D: Blood glucose is not directly impacted by ethambutol therapy.
In summary, monitoring visual acuity is essential due to the potential optic nerve toxicity of ethambutol, making it the most relevant parameter to monitor in this case.
A nurse is caring for a client who the provider suspects might have pernicious anemia. The nurse should expect the provider to prescribe which of the following diagnostic tests?
- A. Schilling test
- B. Complete blood count (CBC)
- C. Vitamin B12 level
- D. Bone marrow biopsy
Correct Answer: A
Rationale: The correct answer is A: Schilling test. Pernicious anemia is caused by vitamin B12 deficiency, often due to poor absorption. The Schilling test is specifically used to diagnose pernicious anemia by evaluating the body's ability to absorb vitamin B12. The test involves giving the patient a small amount of radioactive vitamin B12 to determine how well it is absorbed and utilized by the body. This test helps to differentiate pernicious anemia from other causes of B12 deficiency.
Choice B (Complete blood count) is a general test that may show abnormalities in red blood cells seen in anemia, but it does not specifically diagnose pernicious anemia. Choice C (Vitamin B12 level) alone may not differentiate between pernicious anemia and other causes of B12 deficiency. Choice D (Bone marrow biopsy) is not typically necessary for diagnosing pernicious anemia and is more invasive compared to the Schilling test.
A home health nurse assesses an older adult with vision loss due to glaucoma. What is a safety hazard?
- A. Bright overhead lighting
- B. Presence of scatter rugs in the kitchen
- C. Using contrasting colors in home decor
- D. Wearing slip-resistant shoes
Correct Answer: B
Rationale: The correct answer is B: Presence of scatter rugs in the kitchen. Scatter rugs pose a tripping hazard for individuals with vision loss, especially in areas like the kitchen where spills and slippery surfaces are common. The other choices are incorrect because: A - Bright overhead lighting can actually be beneficial for those with vision loss by improving visibility; C - Using contrasting colors can aid in distinguishing objects and pathways; D - Wearing slip-resistant shoes can help prevent falls.
A nurse is providing discharge teaching to a client who has asthma and new prescriptions for cromolyn and albuterol, both by nebulizer. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will be sure to take the albuterol before taking the cromolyn.
- B. I will take both medications at the same time.
- C. I will take the cromolyn before taking albuterol.
- D. I will take the medications in any order.
Correct Answer: A
Rationale: The correct answer is A: "I will be sure to take the albuterol before taking the cromolyn." This is because albuterol is a bronchodilator that helps to open up the airways quickly, providing immediate relief during an asthma attack. Cromolyn, on the other hand, is a mast cell stabilizer that helps to prevent asthma attacks but does not provide immediate relief. Taking albuterol first allows for quick relief, followed by cromolyn for long-term prevention.
Choice B is incorrect as taking both medications at the same time may not allow for the full effectiveness of each drug. Choice C is incorrect as cromolyn should be taken before albuterol to allow time for it to take effect. Choice D is incorrect as there is a specific order in which these medications should be taken for optimal results.
A nurse is providing teaching to a client who has had a total abdominal hysterectomy and bilateral salpingo-oophorectomy for uterine cancer. Which of the following instructions should the nurse include in the teaching?
- A. Artificial lubrication can be used to treat vaginal itching and dryness.
- B. Avoid sexual activity for the first 6 months.
- C. Use a menstrual pad for vaginal bleeding.
- D. Use a diaphragm for contraception.
Correct Answer: A
Rationale: The correct answer is A: Artificial lubrication can be used to treat vaginal itching and dryness. The rationale for this is that after a total abdominal hysterectomy and bilateral salpingo-oophorectomy, there is a decrease in estrogen levels, leading to vaginal dryness and itching. Using artificial lubrication can help alleviate these symptoms and improve comfort.
Choice B is incorrect as there is no need to avoid sexual activity for 6 months unless specifically advised by the healthcare provider. Choice C is incorrect as there should not be vaginal bleeding after a total abdominal hysterectomy. Choice D is incorrect as using a diaphragm for contraception is not recommended after a hysterectomy.
