NCLEX-RN Exam Practice Questions
Extract:
Question 1 of 5
The primary reason that an increase in heart rate (100 bpm) detrimental to the client with a myocardial infarction (MI) is that:
Correct Answer: D
Rationale: Decreased stroke volume and blood pressure will occur secondary to decreased diastolic filling. Tachycardia primarily decreases diastole; systolic time changes very little. Contractility decreases owing to the decreased filling time and decreased time for fiber lengthening. Decreased O2 supply due to decreased time for filling of the coronary arteries increases ischemia and infarct size. Tachycardia primarily robs the heart of diastolic time, which is the primary time for coronary artery filling.
Question 2 of 5
The nurse is discharging a client with a prescription of eyedrops.
Correct Answer: B
Rationale: Administering a second eyedrop immediately (
B) prevents absorption of the first, indicating a need for teaching (wait 5–10 minutes). Shaking (
A), hand washing (
C), and proper instillation (
D) are correct.
Question 3 of 5
The nurse is teaching a client with a history of allergic rhinitis about self-care. The nurse should tell the client to:
Correct Answer: A
Rationale: Avoiding allergens reduces symptoms in allergic rhinitis, such as sneezing and nasal congestion.
Question 4 of 5
A client is having an amniocentesis. Prior to the procedure, an ultrasound is performed. In preparing the client, the nurse explains the reason for a sonogram in this situation to be:
Correct Answer: C
Rationale: Prior to amniocentesis, the abdomen is scanned by ultrasound to locate the placenta, thus reducing the possibility of penetrating it with the spinal needle used to obtain amniotic fluid.
Question 5 of 5
A 50-year-old depressed client has recently lost his job. He has been reluctant to leave his hospital room. Nursing care would include:
Correct Answer: C
Rationale: The client should be encouraged to attend the unit activities. The nurse and client should choose a few activities for the client to attend that will be positive experiences for him. The nurse should encourage the client to discuss his feelings and to begin to deal with the depression. Depressed persons often have little appetite and poor fluid intake. Constipation is common. A calm, consistent level of stimuli is most effective. Sensory deprivation and overstimulation should be avoided.
