Mock NCLEX RN Exam
Question 1 of 5.
The physician has ordered intubation and mechanical ventilation for a client with periods of apnea following a closed head injury. Arterial blood gases reveal a pH of 7.47, PCO2 of 28, and HCO3 of 23. These findings indicate that the client has:
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis
Explanation: A pH of 7.47 (alkaline) with low PCO2 (28) indicates respiratory alkalosis, likely from hyperventilation due to brain injury. Normal HCO3 rules out metabolic causes.
Question 2 of 5.
The physician has ordered a low-residue diet for a client with Crohn's disease. Which food is not permitted in a low-residue diet?
A. Mashed potatoes
B. Smooth peanut butter
C. Fried fish
D. Rice
Explanation: A low-residue diet minimizes fiber and irritating foods; fried fish is high in fat and can irritate the gut, making it unsuitable for Crohn's disease.
Question 3 of 5.
The physician has ordered Eskalith (lithium carbonate) 500 mg three times a day and Risperdal (risperidone) 2 mg twice daily for a client admitted with bipolar disorder, acute manic episodes. The best explanation for the client's medication regimen is:
A. The client's symptoms of acute mania are typical of undiagnosed schizophrenia.
B. Antipsychotic medication is used to manage behavioral excitement until mood stabilization occurs.
C. The client will be more compliant with a medication that allows some feelings of hypomania.
D. Antipsychotic medication prevents psychotic symptoms commonly associated with the use of mood stabilizers.
Explanation: Risperidone, an antipsychotic, is used to control acute manic symptoms like agitation, while lithium stabilizes mood over time, addressing the immediate behavioral excitement.
Question 4 of 5.
Which one of the following situations represents a maturational crisis for the family?
A. A four-year-old entering nursery school
B. Development of preeclampsia during pregnancy
C. Loss of employment and health benefits
D. Hospitalization of a grandfather with a stroke
Explanation: A maturational crisis involves normal developmental transitions, such as a child entering nursery school, which can stress family dynamics.
Question 5 of 5.
The nurse is making room assignments for four obstetrical clients. If only one private room is available, it should be assigned to:
A. A multigravida with diabetes mellitus
B. A primigravida with preeclampsia
C. A multigravida with preterm labor
D. A primigravida with hyperemesis gravidarum
Explanation: Preeclampsia requires close monitoring due to risks like seizures or stroke, making a private room essential for a primigravida with this condition.
