NCLEX RN Practice Questions Quizlet
1. During an assessment of a client with cardiomyopathy, the nurse finds that the systolic blood pressure has decreased from 145 to 110 mm Hg and the heart rate has risen from 72 to 96 beats per minute, and the client complains of periodic dizzy spells. The nurse instructs the client to:
- A. Increase fluids that are high in protein
- B. Restrict fluids
- C. Force fluids and reassess blood pressure
- D. Limit fluids to non-caffeine beverages
Correct answer: D
Rationale: In this scenario, the client with cardiomyopathy is exhibiting signs of orthostatic hypotension, which is characterized by a significant drop in systolic blood pressure (>15 mm Hg) and an increase in heart rate (>15%), along with dizziness. These symptoms suggest volume depletion, inadequate vasoconstrictor mechanisms, and autonomic insufficiency. The appropriate nursing intervention in this case is to force fluids and reassess blood pressure to address the underlying issue of volume depletion and improve hemodynamic stability. Choices A, B, and D are incorrect because increasing fluids high in protein, restricting fluids, or limiting fluids to non-caffeine beverages are not appropriate actions for a client experiencing orthostatic hypotension and signs of volume depletion.
2. Which of the following can cause coup-contrecoup injuries?
- A. Rotational forces
- B. Deformation forces
- C. Deceleration forces
- D. Acceleration forces
Correct answer: C
Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.
3. Which of the following conditions is a contraindication for performing a diagnostic peritoneal lavage?
- A. A client who is 9 weeks pregnant
- B. A client with a femur fracture
- C. A morbidly obese client
- D. A client with hypertension
Correct answer: C
Rationale: Diagnostic peritoneal lavage is contraindicated in morbidly obese clients due to several reasons. Excess body fat in morbidly obese individuals makes it challenging to locate essential landmarks required for the procedure. Additionally, the equipment utilized for the lavage may not be sized appropriately to accommodate an obese individual. Furthermore, morbid obesity places undue stress on the cardiovascular and respiratory systems, increasing the risk of complications when administering anesthetic agents during the procedure. Therefore, performing a diagnostic peritoneal lavage on a morbidly obese client is not recommended. Choice A, a client who is 9 weeks pregnant, is not a contraindication for diagnostic peritoneal lavage. Pregnancy status alone does not preclude the procedure unless there are specific maternal or fetal concerns. Choice B, a client with a femur fracture, is not a contraindication for diagnostic peritoneal lavage. The presence of a femur fracture does not typically affect the ability to perform this diagnostic procedure. Choice D, a client with hypertension, is not a contraindication for diagnostic peritoneal lavage. Hypertension, while a consideration for anesthesia and surgery, does not directly impact the feasibility of performing a diagnostic peritoneal lavage.
4. The patient in the emergency room has a history of alprazolam (Xanax) abuse and abruptly stopped taking Xanax about 24 hours ago. He presents with visible tremors, pacing, fear, impaired concentration, and memory. Which intervention takes priority?
- A. Have the patient lie down on a stretcher with bed rails raised
- B. Offer the patient a cup of water and a small amount of food
- C. Reassure the patient about his well-being
- D. Inform the physician about the patient's Xanax withdrawal
Correct answer: A
Rationale: The 1-4 day period after Xanax withdrawal is critical as it poses the highest risk of life-threatening seizures. Alprazolam is a benzodiazepine, and sudden cessation can lead to severe withdrawal symptoms. The patient's visible tremors, fear, pacing, and cognitive impairment indicate a state of heightened distress and potential seizure risk. Placing the patient on a stretcher with raised bed rails is essential for seizure precautions, ensuring safety and preventing injury during a potential seizure. Offering water and food, reassuring the patient, or informing the physician about Xanax withdrawal are not immediate priorities compared to managing the risk of seizures in this high-risk situation.
5. A man is receiving heparin subcutaneously. The patient has dementia and lives at home with a part-time caretaker. The nurse is most concerned about which side effect of heparin?
- A. Back Pain
- B. Fever and Chills
- C. Risk for Bleeding
- D. Dizziness
Correct answer: C
Rationale: The correct answer is 'Risk for Bleeding.' A patient with dementia may have impaired judgment and may be prone to falls or injuries, increasing the risk of bleeding while on heparin therapy. Monitoring for signs of bleeding is crucial in this situation. Choice A, 'Back Pain,' is not a common side effect of heparin. Choice B, 'Fever and Chills,' is not a typical side effect of heparin but may indicate other underlying conditions. Choice D, 'Dizziness,' is not a common side effect of heparin and is not the primary concern in this scenario.
