NCLEX-RN Exam Practice Questions
Extract:
Question 1 of 5
The nurse practitioner determines that a client is approximately 9 weeks' gestation. During the visit, the practitioner informs the client about symptoms of physical changes that she will experience during her first trimester, such as:
Correct Answer: A
Rationale: Nausea and vomiting are experienced by almost half of all pregnant women during the first 3 months of pregnancy as a result of elevated human chorionic gonadotropin levels and changed carbohydrate metabolism. Quickening is the mother's perception of fetal movement and generally does not occur until 18-20 weeks after the last menstrual period in primigravidas, but it may occur as early as 16 weeks in multigravidas. During the first trimester there should be only a modest weight gain of 2-4 lb. It is not uncommon for women to lose weight during the first trimester owing to nausea and/or vomiting. Physical changes are not apparent until the second trimester, when the uterus rises out of the pelvis.
Question 2 of 5
An 11-month-old infant is admitted with a possible diagnosis of pyloric stenosis. Which of the following best describes the characteristic clinical manifestations of pyloric stenosis?
Correct Answer: D
Rationale: There is no evidence of pain in infants with pyloric stenosis whether eating or not. There are both good appetite and feeding habits in these children. Because of regurgitation, there is usually decreased frequency and quantity of stools and also signs of dehydration and weight loss. Along with upper abdominal distention, there is a characteristic palpable olive-shaped mass located to the right of the umbilicus.
Question 3 of 5
A 20-year-old female has a prescription for Sumycin (tetracycline). While teaching the client how to take her medicine, the nurse learns that the client is also taking an oral contraceptive. Which instruction should be included in the teaching plan?
Correct Answer: D
Rationale: Tetracyclines can reduce the effectiveness of oral contraceptives by altering gut flora, affecting estrogen metabolism. This increases the risk of unintended pregnancy, requiring backup contraception.
Question 4 of 5
A 48-year-old male client is hospitalized with mild ascites, bruising, and jaundice. He has a 20-year history of alcohol abuse. The client is diagnosed with cirrhosis. His serum ammonia level is high, indicating hepatic encephalopathy. He has esophageal varices. Which of the following may cause the varices to rupture?
Correct Answer: A
Rationale: Lifting heavy objects will increase intrathoracic pressure, thus placing the client at risk for rupturing esophageal varices.
Question 5 of 5
Early in her ninth month of pregnancy, a client has been diagnosed as having mild preeclampsia. In counseling her about her diet, the nurse must emphasize the importance of:
Correct Answer: D
Rationale: Women with pregnancy-induced hypertension have a reduced plasma volume secondary to venous vessel constriction, not hypovolemia; therefore, sodium restriction is not recommended. It is suggested that these women avoid extremely salty foods. Drinking six to eight glasses of water per day facilitates optimal fluid volume and renal perfusion, but it will not decrease the venous vessel constriction of pregnancy-induced hypertension. Carbohydrate needs increase during pregnancy, specifically during the second and third trimesters, but they have not been linked to pregnancy-induced hypertension. Loss of urinary protein (proteinuria) is associated with increased permeability of the large protein molecules with pregnancy-induced hypertension. Additional dietary protein also helps increase the plasma colloidal osmotic pressure. Diets deficient in protein have been linked to pregnancy-induced hypertension.
