NCLEX PN Exam Cram Questions
Extract:
Question 1 of 5
The factor that most determines drug distribution is:
Correct Answer: A
Rationale: The correct answer is 'vascular perfusion of the tissue or organ.' Drug distribution is primarily determined by how well the circulatory system delivers the drug to various tissues and organs. Adequate perfusion ensures proper distribution of the drug throughout the body. While the salt form (choice
B), drug interactions (choice
C), and steady state (choice
D) can influence drug efficacy and metabolism, they are not as crucial as vascular perfusion for the initial distribution of a drug.
Question 2 of 5
When teaching a patient with COPD pulmonary exercises, what should be done?
Correct Answer: A
Rationale: The correct answer is to teach pursed-lip breathing techniques. Pursed-lip breathing helps to decrease the volume of air expelled by keeping the airways open longer, making it easier for patients with COPD to breathe out. Encouraging heavy lifting exercises (
Choice
B) is not suitable for patients with COPD as it can lead to increased shortness of breath. Limiting exercises due to respiratory acidosis (
Choice
C) is not correct; instead, exercises should be tailored to the patient's tolerance. Taking breaks every 10-20 minutes (
Choice
D) is not specific to the management of COPD pulmonary exercises.
Question 3 of 5
A nurse is working in a pediatric clinic, and a 25-year-old mother comes in with a 4-week-old baby. The mother is stressed out about the loss of sleep, and the baby exhibits signs of colic. Which of the following techniques should the nurse teach the mother?
Correct Answer: D
Rationale: Neural warmth techniques involve the caregiver providing a warm, soothing touch to the baby, which can help to lower the baby's agitation level and promote relaxation. This technique is beneficial for calming colicky babies.
Choices A, B, and C are incorrect because distraction with a red object, prone positioning, and tapping reflex techniques are not effective methods for managing colic in infants. Red object distraction is not a proven technique for soothing colicky babies. Prone positioning is not recommended for infants due to the risk of sudden infant death syndrome (SIDS). Tapping reflex techniques are not recognized as effective interventions for colic.
Question 4 of 5
A nurse is assigned to do pre-operative teaching on a blind patient who is scheduled for surgery the following morning. What teaching strategy would best fit the situation?
Correct Answer: A
Rationale: For a blind patient scheduled for surgery the following morning, the best teaching strategy would be verbal teaching in short sessions throughout the day. Providing information in smaller amounts makes it easier to retain, and one-on-one teaching is most effective.
Choice B, providing a pre-operative booklet in Braille, may not be as practical for last-minute teaching.
Choice C, providing an audio recording, may not allow for immediate interaction and clarification.
Choice D, having a family member instruct the patient, may not ensure the accuracy and clarity of the information provided.
Question 5 of 5
A person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?
Correct Answer: A
Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern.
Therefore,
Choice A is the correct answer.
Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.
