ATI NCLEX-RN Practice Questions Questions
Extract:
Question 1 of 5
The physician has ordered atropine sulfate 0.4 milligrams IM before surgery. The medication is supplied in 0.8 milligrams per milliliter. How much medication should the nurse prepare to administer?
Correct Answer: 0.5
Rationale:
To calculate: 0.4 mg desired ÷ 0.8 mg/mL = 0.5 mL. The nurse should prepare 0.5 mL of atropine sulfate.
Question 2 of 5
The nurse is caring for a client with a diagnosis of ectopic pregnancy. Which diagnostic test is most likely to be ordered?
Correct Answer: C
Rationale: Ultrasound confirms the location of the pregnancy (e.g. outside the uterus) and serial serum hCG levels help diagnose ectopic pregnancy by showing abnormal doubling patterns. Both tests are commonly ordered.
Question 3 of 5
The nurse is teaching a client with Parkinson's disease ways to prevent curvatures of the spine associated with the disease. To prevent spinal flexion, the nurse should tell the client to:
Correct Answer: A
Rationale: Lying prone without a pillow helps counteract the forward flexion posture common in Parkinson's disease, reducing spinal curvature. The other positions do not effectively prevent flexion.
Question 4 of 5
Pregnant women with diabetes often have problems related to the effectiveness of insulin in controlling their glucose levels during their second half of pregnancy. The nurse teaches the client that this is due to:
Correct Answer: D
Rationale: There is a rise in glomerular filtration rate in the kidneys in conjunction with decreased tubular glucose reabsorption, resulting in glycosuria. Insulin is inhibited by increased levels of estrogen. Insulin is inhibited by increased levels of progesterone. Human placental lactogen levels increase later in pregnancy. This hormonal antagonist reduces insulin's effectiveness, stimulates lipolysis, and increases the circulation of free fatty acids.
Question 5 of 5
A 28-year-old multigravida has class II heart disease. At her prenatal visit at 34 weeks' gestation, all of the following observations are made. Which would require intervention?
Correct Answer: C
Rationale: This is not an excessive weight gain indicative of fluid retention. The blood pressure is within normal range. Showering should not cause shortness of breath. This could be a sign of cardiac decompensation. Dependent ankle edema is normal late in the day among pregnant women. Progressive edema would be a dangerous development.
