NCLEX RN Exam Review Answers
1. The healthcare provider is reviewing the lab results of a patient who has presented in the Emergency Room. The lab results show that the troponin T value is at 5.3 ng/mL. Which of these interventions, if not already completed, would take priority over the others?
- A. Place the patient in a 90-degree position
- B. Assess whether the patient is taking diuretics
- C. Obtain and attach defibrillator leads
- D. Assess the patient's last ejection fraction
Correct answer: C
Rationale: In this scenario, the elevated Troponin T level indicates cardiac damage, possibly due to a myocardial infarction. A Troponin T value of 5.3 ng/mL is significantly elevated (normal levels are below 0.2 ng/mL), suggesting acute cardiac injury. Given the setting of an Emergency Room and the critical nature of the situation, the priority intervention should be to obtain and attach defibrillator leads. Elevated Troponin T levels can indicate a higher risk of arrhythmias, including ventricular fibrillation, which can lead to sudden cardiac arrest. Defibrillator leads are essential for monitoring the patient's cardiac rhythm and readiness for immediate defibrillation if necessary. Placing the patient in a 90-degree position (Choice A) or assessing diuretic use (Choice B) are not immediate priorities in this critical situation. Additionally, assessing the patient's last ejection fraction (Choice D) is important but not as urgent as preparing for potential life-threatening arrhythmias requiring defibrillation.
2. An 85-year-old client is diagnosed with hypernatremia due to lack of fluid intake and dehydration. The nurse knows that symptoms of hypernatremia include:
- A. Lack of thirst
- B. Pale skin
- C. Hypertension
- D. Swollen tongue
Correct answer: D
Rationale: Hypernatremia among elderly clients can result from dehydration and insufficient fluid intake, leading to sodium levels above 145 mEq/L. Common symptoms of hypernatremia include mental status changes, a thick or swollen tongue, excessive thirst, and flushed skin. Choice A, 'Lack of thirst,' is incorrect as hypernatremia typically presents with excessive thirst. Choice B, 'Pale skin,' is not a typical symptom of hypernatremia. Choice C, 'Hypertension,' is not a direct symptom of hypernatremia and is more commonly associated with other conditions like hypertension itself.
3. The healthcare provider is educating a parent about side effects of routine immunizations. Which of the following must be reported immediately?
- A. Irritability
- B. Slight edema at the injection site
- C. Local tenderness
- D. Temperature of 102.5?F
Correct answer: D
Rationale: A temperature of 102.5°F or higher following immunization is considered an adverse reaction and should be reported immediately. This could indicate a more serious systemic response to the vaccine. Irritability, slight edema at the injection site, and local tenderness are common, mild side effects of routine immunizations and do not typically require immediate reporting. Other reactions that should be reported immediately include excessive crying for more than 3 hours, seizure activity, and the presence of tender, swollen, or reddened areas at the injection site.
4. A 4-year-old child with acute glomerulonephritis is admitted to the hospital. The nurse identifies which client problem in the plan of care as the priority?
- A. Infection related to hypertension
- B. Injury related to loss of blood in urine
- C. Excessive fluid volume related to decreased plasma filtration
- D. Retarded growth and development related to a chronic disease
Correct answer: C
Rationale: In acute glomerulonephritis, the child experiences excessive accumulation of water and retention of sodium, leading to circulatory congestion and edema. Excessive fluid volume is a primary concern due to the disease process. Hypertension and infection are not directly related to acute glomerulonephritis; therefore, they are not the priority client problems. While hematuria (blood in urine) may occur, it typically does not lead to significant injury that takes precedence over excessive fluid volume. Acute glomerulonephritis is an acute condition, not chronic; therefore, retarded growth and development related to a chronic disease is not the priority issue. With proper management, most children recover completely without long-term growth and development issues.
5. A child diagnosed with Hepatitis A is under the care of a healthcare provider. Which of the following precautions would be most important to take to prevent the transmission of this infectious disease?
- A. Encourage the Hepatitis A vaccine for family members and siblings
- B. Use needleless systems if possible; otherwise, use careful needle precautionary measures
- C. Teach the child and enforce strict and frequent hand washing
- D. Teach the child and family about the dangers of contaminated food and water
Correct answer: C
Rationale: The most crucial precaution to prevent the transmission of Hepatitis A is to emphasize strict and frequent hand washing. Hepatitis A is a virus that spreads through the oral-fecal route and can survive on human hands. Hand washing is the most effective measure to reduce the risk of transmission. Encouraging the Hepatitis A vaccine for family members and siblings (Choice A) is beneficial for prevention but not as directly impactful as hand washing. While needle precautions (Choice B) are important in healthcare settings, they are not directly relevant to preventing the spread of Hepatitis A. Teaching about the dangers of contaminated food and water (Choice D) is important for general hygiene but may not be as effective as emphasizing hand hygiene in preventing the spread of Hepatitis A.
