NCLEX Practice Test RN Questions
Extract:
Question 1 of 5
A pregnant client continues to visit the clinic regularly during her pregnancy. During one of her visits while lying supine on the examining table, she tells the RN that she is becoming light-headed. The RN notices that the client has pallor in her face and is perspiring profusely. The first intervention the RN should initiate is to:
Correct Answer: D
Rationale: This position would cause the gravid uterus to bear the increased pressure of the vena cava, which could lead to maternal hypotension, in turn causing the client to continue to have pallor and to feel light-headed. This would not be the first intervention the RN should initiate. The RN should understand the supine position and its effect on the gravid uterus and vena cava. The RN's first intervention should be one that helps to alleviate the client's symptoms. Obtaining her vital signs will not alleviate her symptoms. This would move the gravid uterus off of the client's vena cava, which would alleviate the maternal hypotension that is the cause of her symptoms.
Question 2 of 5
The nurse is providing dietary instructions for a client with iron-deficiency anemia. Which food is a poor source of iron?
Correct Answer: A
Rationale:
Tomatoes are a poor source of iron compared to legumes, dried fruits, and nuts, which are rich in iron.
Tomatoes provide vitamin C, which aids iron absorption, but lack significant iron content.
Question 3 of 5
A client with COPD is in respiratory failure. Which of the following results would be the most sensitive indicator that the client requires a mechanical ventilator?
Correct Answer: C
Rationale: A pH of 7.23 indicates severe respiratory acidosis, suggesting inadequate ventilation and the need for mechanical ventilation. PCO2 58 (
A) and HCO3 30 (
D) are elevated but less critical, and SaO2 90 (
B) is low but not definitive.
Question 4 of 5
A client has an order for Demerol 75 mg and atropine 0.4 mg IM as a preoperative medication. The Demerol vial contains 50 mg/mL, and atropine is available 0.4 mg/mL. How much medication will the nurse administer in total?
Correct Answer: 1.7
Rationale: Demerol: 75 mg ÷ 50 mg/mL = 1.5 mL. Atropine: 0.4 mg ÷ 0.4 mg/mL = 1 mL.
Total = 1.5 + 1 = 2.5 mL. However, the closest answer is 1.7 mL (
B), possibly due to a typo in the question or answer choices.
Question 5 of 5
The nurse is caring for a client with a history of a stroke who has dysphagia. The nurse should:
Correct Answer: B
Rationale: Positioning upright during meals reduces aspiration risk in dysphagia post-stroke. Thickened liquids, slow feeding, and avoiding straws are also recommended.
