Exam Cram NCLEX RN Practice Questions

1. Which of the following can cause coup-contrecoup injuries?

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.

2. What would be the most appropriate follow-up by the home care nurse for a 57-year-old male client with a hemoglobin of 10 g/dl and a hematocrit of 32%?

Correct answer: A

Rationale: The correct answer is to ask the client if he has noticed any bleeding or dark stools. Normal hemoglobin for males is 13.0 - 18 g/dl, and normal hematocrit for males is 42 - 52%. The values of hemoglobin and hematocrit provided for the client are below normal, indicating mild anemia. The first step for the nurse is to inquire about any signs of bleeding or changes in stools that could suggest bleeding from the gastrointestinal tract. This helps in assessing the possible cause of the low hemoglobin and hematocrit levels. The other options are not appropriate as calling 911 and going to the emergency department immediately is not warranted for mild anemia, scheduling a repeat test in 1 month delays addressing the current concern, and referring the client to a hematologist may be premature without investigating the cause of the low levels first.

3. A 30-year-old woman is experiencing anaphylaxis from a bee sting. Emergency personnel have been called. The nurse notes the woman is breathing but short of breath. Which of the following interventions should the nurse do first?

Correct answer: C

Rationale: In a situation where a patient is experiencing anaphylaxis, it is crucial to act swiftly. Asking the woman if she carries an emergency medical kit is the most appropriate initial intervention. Many individuals with a history of anaphylaxis carry epinephrine auto-injectors, such as epi-pens, which can be life-saving in such situations. Initiating cardiopulmonary resuscitation (CPR) is not indicated as the patient is breathing but short of breath, and CPR is not the first-line intervention for anaphylaxis. Checking for a pulse, though important, is not the initial priority in managing anaphylaxis. Staying with the woman until help arrives is essential for providing support and monitoring her condition, but confirming the availability of an emergency medical kit takes precedence to promptly address the anaphylactic reaction.

4. Which of the following conditions is a contraindication for performing a diagnostic peritoneal lavage?

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.

5. A nurse caring for several patients in the cardiac unit is told that one is scheduled for implantation of an automatic internal cardioverter-defibrillator. Which of the following patients is most likely to have this procedure?

Correct answer: C

Rationale: The correct answer is a patient with a history of ventricular tachycardia and syncopal episodes. An automatic internal cardioverter-defibrillator is used to deliver an electric shock to the heart to terminate episodes of ventricular tachycardia and ventricular fibrillation. These patients are at high risk of life-threatening arrhythmias, which may result in syncope. Patients with atrial tachycardia and fatigue (Choice D) would not typically require an implantable cardioverter-defibrillator as their primary issue is related to atrial arrhythmias. Patients who have had a myocardial infarction without cardiac muscle damage (Choice A) or postoperative coronary bypass patients recovering on schedule (Choice B) are not necessarily at high risk for ventricular arrhythmias and would not be the primary candidates for an implantable cardioverter-defibrillator.
