The nurse is preparing a client diagnosed with Graves' disease to receive radioactive iodine therapy. What information should the nurse share with the client about the therapy?
- A. After the initial dose, subsequent treatments must continue lifelong.
- B. The radioactive iodine is designed to destroy the entire thyroid gland with just one dose.
- C. It takes 6 to 8 weeks after treatment to experience relief from the symptoms of the disease.
- D. High radioactivity levels prohibit contact with family for 4 weeks after the initial treatment.
Correct Answer: C
Rationale: Graves' disease is also known as toxic diffuse goiter and is characterized by a hyperthyroid state resulting from hypersecretion of thyroid hormones. After treatment with radioactive iodine therapy, a decrease in the thyroid hormone level should be noted, which helps alleviate symptoms. Relief of symptoms does not occur until 6 to 8 weeks after initial treatment. Occasionally, a client may require a second or third dose, but treatments are not lifelong. This form of therapy is not designed to destroy the entire gland; rather, some of the cells that synthesize thyroid hormone will be destroyed by the local radiation. The nurse must reassure the client and family that unless the dosage is extremely high, clients are not required to observe radiation precautions. The rationale for this is that the radioactivity quickly dissipates.

The nurse suspects that an air embolism has occurred when the client's central venous catheter disconnects from the intravenous (IV) tubing. The nurse immediately places the client on her or his left side in which position?
- A. High Fowler's
- B. Trendelenburg's
- C. Lateral recumbent
- D. Reverse Trendelenburg's
Correct Answer: B
Rationale: If the client develops an air embolism, the immediate action is to place the client in Trendelenburg's position on the left side. This position raises the client's feet higher than the head and traps any air in the right atrium. If necessary, the air can then be directly removed by intracardiac aspiration.
The nurse is caring for a newly delivered breast-feeding infant. Which intervention performed by the nurse would best prevent jaundice in this infant?
- A. Placing the infant under phototherapy
- B. Keeping the infant NPO until the second period of reactivity
- C. Encouraging the mother to breast-feed the infant every 2 to 3 hours
- D. Encouraging the mother to supplement breast-feeding with formula
Correct Answer: C
Rationale: To help prevent jaundice, the mother should feed the infant frequently in the immediate birth period because colostrum is a natural laxative and helps promote the passage of meconium. Breast-feeding should begin as soon as possible after birth while the infant is in the first period of reactivity.
The nurse is caring for a client who is receiving tacrolimus daily. Which finding indicates to the nurse that the client is experiencing an adverse effect of the medication?
- A. Hypotension
- B. Photophobia
- C. Profuse sweating
- D. Decrease in urine output
Correct Answer: D
Rationale: Tacrolimus is an immunosuppressant medication used in the prophylaxis of organ rejection in clients receiving allogenic liver transplants. Adverse reactions and toxic effects include nephrotoxicity and pleural effusion. Nephrotoxicity is characterized by an increasing serum creatinine level and a decrease in urine output. Frequent side effects include headache, tremor, insomnia, paresthesia, diarrhea, nausea, constipation, vomiting, abdominal pain, and hypertension. None of the other options are associated with an adverse reaction to this medication.
The nurse is performing pin-site care on a client in skeletal traction. Which normal finding should the nurse expect to note when assessing the pin sites?
- A. Loose but intact pin sites
- B. Clear drainage from the pin sites
- C. Purulent drainage from the pin sites
- D. Redness and swelling around the pin sites
Correct Answer: B
Rationale: A small amount of clear drainage ('weeping') may be expected after cleaning and removing crusting around the pin sites of skeletal traction. Pins should not be loose; if this is noted, the primary health care provider should be notified. Purulent drainage and redness and swelling around the pin sites may be indicative of an infection.
A client who survived a house fire is experiencing respiratory distress, and an inhalation injury is suspected. What should the nurse monitor to determine the presence of carbon monoxide poisoning?
- A. Pulse oximetry
- B. Urine myoglobin
- C. Sputum carbon levels
- D. Serum carboxyhemoglobin levels
Correct Answer: D
Rationale: Serum carboxyhemoglobin levels are the most direct measure of carbon monoxide poisoning, provide the level of poisoning, and thus determine the appropriate treatment measures. The carbon monoxide molecule has a 200 times greater affinity for binding with hemoglobin than an oxygen molecule, causing decreased availability of oxygen to the cells. Clients are treated with 100% oxygen under pressure (hyperbaric oxygen therapy). Options 1, 2, and 3 would not identify carbon monoxide poisoning.
