Which of the following is the best indicator of the diagnosis of HIV? ❍ A. White blood cell count ❍ B. ELISA ❍ C. Western Blot ❍ D. Complete blood count
Answer C is correct. The most definitive diagnostic tool for HIV is the Western Blot. The white blood cell count, as stated in answer A, is not the best indicator, but a white blood cell count of less than 3,500 requires investigation. The ELISA test, answer B, is a screening exam. Answer D is not specific enough.
The client presents to the emergency room with a “bull’s eye” rash. Which question would be most appropriate for the nurse to ask the client?
❍ A. “Have you found any ticks on your body?”
❍ B. “Have you had any nausea in the last 24 hours?”
❍ C. “Have you been outside the country in the last 6 months?”
❍ D. “Have you had any fever for the past few days?”
Answer A is correct. The “bull’s eye” rash is indicative of Lyme’s disease, a disease spread by ticks. The signs and symptoms include elevated temperature, headache, nausea, and the rash. Although answers B and D are important, the question asked which question would be best . Answer C has no significance.

❍ B. The infant with meningitis
❍ C. The elderly client with a thyroidectomy 4 days ago
❍ D. The client with a thoracotomy 2 days ago
Answer C is correct. The client that needs the least-skilled nursing care is the client with the thyroidectomy 4 days ago. Answers A, B, and D are incorrect because the other clients are less stable and require a registered nurse.
The client presents to the emergency room with a hyphema. Which action by the nurse would be best?
❍ A. Elevate the head of the bed and apply ice to the eye
❍ B. Place the client in a supine position and apply heat to the knee
❍ C. Insert a Foley catheter and measure the intake and output

The client has an order for FeSo 4 liquid. Which method of administration would be best?
❍ A. Administer the medication with milk
❍ B. Administer the medication with a meal
❍ C. Administer the medication with orange juice
❍ D. Administer the medication undiluted
Answer C is correct. FeSO 4 or iron should be given with ascorbic acid (vitamin C). This helps with the absorption. It should not be given with meals or milk because this decreases the absorption; thus, answers A and B are incorrect. Giving it undiluted, as stated in answer D, is not good because it tastes bad.
The client with an ileostomy is being discharged. Which teaching should be included in the plan of care?
❍ A. Using Karaya powder to seal the bag.
❍ B. Irrigating the ileostomy daily.
❍ C. Using stomahesive as the best skin protector.
❍ D. Using Neosporin ointment to protect the skin.
Answer C is correct. The best protector for the client with an ileostomy to use is stomahesive. Answer A is not correct because the bag will not seal if the client uses Karaya powder. Answer B is incorrect because there is no need to irrigate an ileostomy. Neosporin, answer D, is not used to protect the skin because it is an antibiotic.
Vitamin K is administered to the newborn shortly after birth for which of the following reasons? ❍ A. To stop hemorrhage ❍ B. To treat infection ❍ C. To replace electrolytes ❍ D. To facilitate clotting
Answer D is correct. Vitamin K is given after delivery because the newborn’s intestinal tract is sterile and lacks vitamin K needed for clotting.

Before administering Methyltrexate orally to the client with cancer, the nurse should check the: ❍ A. IV site ❍ B. Electrolytes ❍ C. Blood gases ❍ D. Vital signs
Answer D is correct. The vital signs should be taken before any chemotherapy agent. If it is an IV infusion of chemotherapy, the nurse should check the IV site as well. Answers B and C are incorrect because it is not necessary to check the electrolytes or blood gasses

Answer C is correct. Before chemotherapy, an antiemetic should be given because most chemotherapy agents cause nausea. It is not necessary to give a bolus of IV fluids, medicate for pain, or allow the client to eat; therefore, answers A, B, and D are incorrect
The client is admitted to the postpartum unit with an order to continue the infusion of Pitocin. The nurse is aware that Pitocin is working if the fundus is:
❍ A. Deviated to the left.
❍ B. Firm and in the midline.
❍ C. Boggy.
❍ D. Two finger breadths below the umbilicus.
Answer B is correct. Pitocin is used to cause the uterus to contract and decrease bleeding. A uterus deviated to the left, as stated in answer A, indicates a full bladder. It is not desirable to have a boggy uterus, making answer C incorrect. This lack of muscle tone will increase bleeding. Answer D is incorrect because Pitocin does not affect the position of the uterus.

❍ B. “When drawing up my insulin, I should draw up the NPH insulin first.”
❍ C. “It doesn’t matter which insulin I draw up first.”
❍ D. “I cannot mix the insulin, so I will need two shots.”
Answer A is correct. Regular insulin should be drawn up before the NPH. They can be given together, so there is no need for two injections, making answer D incorrect.
Answer B is obviously incorrect, and answer C is incorrect because it certainly does matter which is drawn first: Contamination of NPH into regular insulin will result in a hypoglycemic reaction at unexpected times.
The client is scheduled to have an intravenous cholangiogram. Before the procedure, the nurse should assess the patient for: ❍ A. Shellfish allergies ❍ B. Reactions to blood transfusions ❍ C. Gallbladder disease ❍ D. Egg allergies
