1. Answer A is correct.

 The major complication of SLE is lupus nephritis, which results in end-stage renal disease. SLE affects the musculoskeletal, integumentary, renal, nervous, and cardiovascular systems, but the major complication is renal involvement; therefore, answers B and D are incorrect. Answer C is incorrect because the SLE produces a “butterfly” rash, not desquamation. 


2. Answer A is correct. Finasteride is an androgen inhibitor; therefore, women who are pregnant or who might become pregnant should be told to avoid touching the tablets. Answer B is incorrect because there are no benefits to giving the medication with food. Answer C is incorrect because the medication can take 6 months to a year to be effective. Answer D is not an accurate statement; therefore, it is incorrect. 




3. Answer D is correct. 
The nurse can expect to find the presence of Trendelenburg sign. (While bearing weight on the affected hip, the pelvis tilts downward on the unaffected side instead of tilting upward, as expected with normal stability). Scarf sign is a characteristic of the preterm newborn; therefore, answer A is incorrect. Harlequin sign can be found in normal newborns and indicates transient changes in circulation; therefore, answer B is incorrect. Answer C is incorrect because Cullen’s sign is an indication of intra-abdominal bleeding. 




4. Answer C is correct.
 A diet that is high in fat and refined carbohydrates increases the risk of colorectal cancer. High fat content results in an increase in fecal bile acids, which facilitate carcinogenic changes. Refined carbohydrates increase the transit time of food through the gastrointestinal tract and increase the exposure time of the intestinal mucosa to cancer-causing substances. Answers A, B, and D do not relate to the question; therefore, they are incorrect. 



5. Answer B is correct. 
The nurse should avoid giving the infant a pacifier or bottle because sucking is not permitted. Holding the infant cradled in the arms, providing a mobile, and offering sterile water using a Breck feeder are permitted; therefore, answers A, C, and D are incorrect. 



6. Answer A is correct. 
The client with asterixis or “flapping tremors” will have irregular flexion and extension of the wrists when the arms are extended and the wrist is hyperextended with the fingers separated. Asterixis is associated with hepatic encephalopathy. Answers B, C, and D do not relate to asterixis; therefore, they are incorrect. 




7. Answer D is correct. 
The client with esophageal varices might develop spontaneous bleeding from the mechanical irritation caused by taking capsules; therefore, the nurse should request the medication in an alternative form such as a suspension. Answer A is incorrect because it does not best meet the client’s needs. Answer B is incorrect because it is not the best means of preventing bleeding. Answer C is incorrect because the medications should not be given with milk or antacids. 





8. Answer A is correct. 
Surgical repair of an inguinal hernia is recommended to prevent strangulation of the bowel, which could result in intestinal obstruction and necrosis. Answer B does not relate to an inguinal hernia; therefore, it is incorrect. Bile salts,which are important to the digestion of fats, are produced by the liver, not the intestines; therefore, answer C is incorrect. Repair of the inguinal hernia will prevent swelling and obstruction associated with strangulation, but it will not increase intestinal motility; therefore, answer D is incorrect. 





9. Answer A is correct. Tomatoes are a poor source of iron, although they are an excellent source of vitamin C, which increases iron absorption. Answers B, C, and D are good sources of iron; therefore, they are incorrect. 





10. Answer D is correct. Serum amylase levels greater than 200 units/dL help confirm the diagnosis of acute pancreatitis.

11. Answer A is correct. Periodically lying in a prone position without a pillow will help prevent the flexion of the spine that occurs with Parkinson’s disease. Answers B and C flex the spine; therefore, they are incorrect. Answer D is not realistic because position changes during sleep; therefore, it is incorrect. 





12. Answer C is correct. The medication should be administered slowly (no more than 50mg per minute); otherwise, cardiac arrhythmias can occur.

13. Answer B is correct. The client recovering from acute pancreatitis needs a diet that is high in calories and low in fat. Answers A, C, and D are incorrect because they can increase the client’s discomfort. 




14. Answer A is correct. The client with polycythemia vera has an abnormal increase in the number of circulating red blood cells that results in increased viscosity of the blood.

15. Answer B is correct. Dressing in extra layers of clothing will help decrease the feeling of being cold that is experienced by the client with hypothyroidism. Decreased sensation and decreased alertness are common in the client with hypothyroidism. The use of electric blankets and heating pads can result in burns, making answers A and C incorrect. Answer D is incorrect because the client with hypothyroidism has dry skin, and a hot bath morning and evening would make her condition worse.
