ATI NCLEX-RN Practice Questions Questions
Extract:
Question 1 of 5
Four days after delivery, a client develops complications of postpartal hemorrhage. The most common cause of late postpartal hemorrhage is:
Correct Answer: B
Rationale: Late postpartum hemorrhage (after 24 hours) is most commonly caused by retained placental fragments, which prevent uterine contraction and cause bleeding. Uterine atony is more common early postpartum.
Question 2 of 5
The nurse caring for a client receiving intravenous magnesium sulfate must closely observe for side effects associated with drug therapy. An expected side effect of magnesium sulfate is:
Correct Answer: B
Rationale: Hypersomnolence (drowsiness) is an expected side effect of magnesium sulfate used for preeclampsia due to its central nervous system depressant effects. Absence of reflexes or decreased respiratory rate would indicate toxicity not an expected effect.
Question 3 of 5
A 52-year-old female client is admitted to the hospital in acute renal failure. She has been on hemodialysis for the past 2 years. Stat arterial blood gases are drawn on the client yielding the following results: pH 7.30, PCO2 51 mm Hg, HCO3 18 mEq/L, PaO2 84 mm Hg. The nurse would interpret these results as:
Correct Answer: D
Rationale: Compensated metabolic alkalosis would be reflected by the following: pH within normal limit (7.35-7.45), PCO2 >45 mm Hg, HCO3 >26 mEq/L. Respiratory acidosis would be reflected by the following: pH <7.35, PCO2 >45 mm Hg, HCO3 within normal limits (22-26 mEq/L). Partially compensated metabolic alkalosis would be reflected by the following: pH >7.45, PCO2 >45 mm Hg, HCO3 >26 mEq/L. Combined respiratory and metabolic acidosis would be reflected by the following: pH <7.35, PCO2 >45 mm Hg, HCO3 <22 mEq/L.
Question 4 of 5
A male client has experienced low back pain for several years. He is the primary support of his wife and six children. Although he would qualify for disability, he plans to continue his employment as long as possible. His back pain has increased recently, and he is unable to control it with non-steroidal anti-inflammatory agents. He refuses surgery and cannot take narcotics and remain alert enough to concentrate at work. His physician has suggested application of a transcutaneous electrical nerve stimulation (TENS) unit. Which of the following is an appropriate rationale for using a TENS unit for relief of pain?
Correct Answer: C
Rationale: TENS units do not have this effect, but whirlpool therapy does. TENS units do not produce endogenous opioids, only the body can do that. TENS units do work based on the gate-control theory of pain control. TENS units do not have this effect, but possibly changing the client's position would.
Question 5 of 5
Which of the following signs and symptoms indicates a tension pneumothorax as compared to an open pneumothorax?
Correct Answer: C
Rationale: The tension pneumothorax acts like a one-way valve so that the pneumothorax increases with each breath. Eventually, it occupies enough space to shift mediastinal tissue toward the unaffected side away from the midline. Tracheal deviation, movement of point of maximum impulse, and decreased cardiac output will occur. The other three options will occur in both types of pneumothorax.
