Question 1 of 5
A client has been taking lithium 300 mg po bid for the past two weeks. This morning her lithium level was 1 mEq/L. The nurse should:
Correct Answer: C
Rationale: There is no need to phone the physician because the lithium level is within therapeutic range and because there are no indications of toxicity present. There is no reason to withhold the lithium because the blood level is within therapeutic range. Also, it is necessary to give the medication as scheduled to maintain adequate blood levels. The lab results indicate that the client's lithium level is within therapeutic range (0.2-1.4 mEq/L), so the medication should be given as ordered. Benztropine is an antiparkinsonism drug frequently given to counteract extrapyramidal symptoms associated with the administration of antipsychotic drugs (not lithium).
Question 2 of 5
Which food selection would provide the most calcium for a client who is four months pregnant?
Correct Answer: C
Rationale: Yogurt is a rich source of calcium essential for fetal bone development during pregnancy. One cup provides approximately 300-400 mg of calcium significantly more than oatmeal bran muffins or oranges.
Question 3 of 5
The nurse is caring for a client with a history of a hysterectomy. The client complains of hot flashes. The nurse should:
Correct Answer: C
Rationale: Hot flashes post-hysterectomy are due to hormonal changes. Discussing hormone replacement therapy with the physician is appropriate. Heating pads, fluid restriction, and acetaminophen are ineffective.
Question 4 of 5
The nurse is caring for a patient hospitalized with leukopenia. Which of the following assessments should be reported to the physician immediately?
Correct Answer: C
Rationale: A temperature increase to 99.8°F in a patient with leukopenia (low white blood cell count) may indicate an infection which is a medical emergency due to the patient’s compromised immune system. The other vital signs are within normal limits and less urgent.
Question 5 of 5
A client with a deep decubitus ulcer is receiving therapy in the hyperbaric oxygen chamber. Before therapy, the nurse should:
Correct Answer: B
Rationale: Clean, dry skin is required before hyperbaric oxygen therapy to prevent infection and ensure effective oxygen delivery. Lotions, petroleum, or dressings can interfere or pose fire risks.
