An adult client with hyperkalemia is prescribed sodium polystyrene sulfonate. Which serum potassium level is a clinical indicator of effective therapy?
- A. 4.9 mEq/L (4.9 mmol/L)
- B. 5.4 mEq/L (5.4 mmol/L)
- C. 5.8 mEq/L (5.8 mmol/L)
- D. 6.2 mEq/L (6.2 mmol/L)
Correct Answer: A
Rationale: The normal serum potassium level for an adult is 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). Option 1 is the only option that reflects a value within this range. The remaining options identify hyperkalemic levels.

A client is seen in the health care clinic, and a diagnosis of conjunctivitis is made. The nurse provides instructions to the client regarding the care of the disorder while at home. Which statement by the client indicates the need for further instruction?
- A. I can use an ophthalmic analgesic ointment at night if I have eye discomfort.
- B. I do not need to be concerned about spreading this infection to others in my family.
- C. I should apply warm compresses before instilling antibiotic drops if purulent discharge is present in my eye.
- D. I should perform saline eye irrigation before instilling the antibiotic drops into my eye if purulent discharge is present.
Correct Answer: B
Rationale: Conjunctivitis is highly contagious. Antibiotic drops are usually administered four times a day. Ophthalmic analgesic ointment or drops may be instilled, especially at bedtime because discomfort becomes more noticeable when the eyelids are closed. When purulent discharge is present, saline eye irrigations or applications of warm compresses to the eye may be necessary before instilling the medication.
A client regularly takes nonsteroidal antiinflammatory drugs (NSAIDs) and misoprostol has been added to the medication regimen. The nurse should monitor the client for the relief of which sign/symptom?
- A. Diarrhea
- B. Bleeding
- C. Infection
- D. Epigastric pain
Correct Answer: D
Rationale: The client who regularly takes NSAIDs is prone to gastric mucosal injury, which gives the client epigastric pain as a symptom. Misoprostol is administered to prevent this occurrence. Diarrhea can be a side effect of the medication, but its relief is not an intended effect. Bleeding and infection are unrelated to the question.
A client has just taken a dose of trimethobenzamide. When the client states relief of which sign/symptom, is it appropriate for the nurse to determine that the medication has been effective?
- A. Nausea
- B. Heartburn
- C. Constipation
- D. Abdominal pain
Correct Answer: A
Rationale: Trimethobenzamide is an antiemetic agent that is used for the treatment of nausea and vomiting. The medication is not used to treat heartburn, constipation, or abdominal pain.
The nurse reviews the nursing care plan of a hospitalized preschool child who is immobilized as a result of skeletal traction. The nurse notes concerns related to the child's development because of immobilization and hospitalization. Which evaluative statement indicates a positive outcome for the child?
- A. The fracture heals without complications.
- B. The caregivers verbalize safe and effective home care.
- C. The child maintains normal joint and muscle integrity.
- D. The child displays age-appropriate developmental behaviors.
Correct Answer: D
Rationale: Regression and inappropriate developmental behaviors may be displayed in response to immobilization and hospitalization. With individualized care planning, a positive outcome of age-appropriate behavior can be achieved. The remaining options are appropriate evaluative statements for an immobilized child, but they do not directly address the child's development.
The nurse is reviewing the results of a client's phenytoin level that was drawn that morning. The nurse is preparing to discharge once the level is therapeutic. Which result indicates that this goal has been met?
- A. 3 mcg/mL (11.9 mcmol/L)
- B. 8 mcg/mL (31.7 mcmol/L)
- C. 15 mcg/mL (59.5 mcmol/L)
- D. 24 mcg/mL (95.2 mcmol/L)
Correct Answer: C
Rationale: The therapeutic range for serum phenytoin levels is 10 to 20 mcg/mL (39.68 to 79.36 mcmol/L) in clients with normal serum albumin levels and renal function. A level below this range indicates that the client is not receiving sufficient medication and is at risk for seizure activity. In this case, the medication dose should be adjusted upward. A level above the therapeutic range indicates that the client is entering the toxic range and is at risk for toxic side effects of the medication.
