NCLEX RN Exam Review Answers
1. You are caring for a group of elderly clients, many of whom are affected by multiple chronic disorders and are also, at times, affected by some acute disorders that require medical and nursing attention. As you are caring for these clients, some will need a new medication regimen for an acute disorder. You should consider the fact that the elderly population is at risk for more side effects, adverse drug reactions, and toxicity due to the elderly having a(n):
- A. Increased creatinine clearance.
- B. Impaired immune system.
- C. Decreased hepatic metabolism.
- D. Increased bodily fat
Correct answer: C
Rationale: The correct answer is 'Decreased hepatic metabolism.' The elderly population is at risk for more side effects, adverse drug reactions, and toxicity due to a decrease in hepatic metabolism. This is caused by changes in hepatic functioning in the elderly, including decreased hepatic blood flow and functioning. Choice A, 'Increased creatinine clearance,' is incorrect as aging typically results in decreased, not increased, creatinine clearance. Choice B, 'Impaired immune system,' is not directly related to the increased risk of adverse drug reactions in the elderly. Choice D, 'Increased bodily fat,' is not a primary factor contributing to the increased risk of medication-related issues in the elderly population.
2. You are turning your patient in bed and notice that a confused and lethargic patient had loose car keys and lipstick in the bed and had been lying on them. What is this person at risk for due to all three of these factors: confusion, lethargy, and items in the bed?
- A. Falls
- B. Skin breakdown
- C. Apnea
- D. Lack of mobility
Correct answer: B
Rationale: This patient is at great risk for skin breakdown due to the presence of three specific risk factors: confusion, lethargy, and items in the bed. While confusion puts the patient at risk for falls, confusion and lethargy together may lead to a lack of mobility. However, skin breakdown is the primary concern in this scenario as it is associated with all three risk factors - confusion, lethargy, and the presence of items in the bed. Therefore, the correct answer is 'Skin breakdown'.
3. A client with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?
- A. Peaked T waves on the ECG
- B. Muscle spasms
- C. Constipation
- D. A prominent U wave on the ECG
Correct answer: A
Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (Choice B) are more commonly associated with hypocalcemia. Constipation (Choice C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (Choice D) is associated with hypokalemia, not hyperkalemia.
4. A client has started sweating profusely due to intense heat. His overall luid volume is low and he has developed electrolyte imbalance. This client is most likely suffering from:
- A. Malignant hyperthermia
- B. Heat exhaustion
- C. Heat stroke
- D. Heat cramps
Correct answer: B
Rationale: Heat exhaustion occurs when a person has enough diaphoresis that he becomes dehydrated. Intense sweating can cause both luid and electrolyte imbalances. Untreated heat exhaustion can lead to heat stroke, which results in organ damage, loss of consciousness, or death.
5. Mr. K is admitted to the orthopedic unit one morning in preparation for a total knee replacement to start in two hours. Which of the following is a priority topic to instruct this client on admission?
- A. The approximate length of the surgery
- B. The type of anticoagulants that will be prescribed
- C. The time of the next meal of solid food
- D. The length of time until the client can return to work
Correct answer: A
Rationale: The priority topic to instruct a client admitted for a total knee replacement surgery should be the approximate length of the surgery. Pre-surgical teaching should focus on preparing the client for the upcoming procedure. Providing information about the duration of the surgery can help manage the client's expectations, reduce anxiety, and ensure they are mentally prepared for the operation. While details about post-operative care, anticoagulants, meals, and return to work are important, they are not the immediate priority during the preoperative phase. These aspects can be addressed at a later stage in the client's care journey.
