Question 1 of 5
The nurse is administering sucralfate to a client with stomatitis secondary to chemotherapy. The client wants to take the medication after breakfast. How should the nurse respond?
Correct Answer: D
Rationale: Sucralfate forms a protective barrier over irritated stomach and intestinal areas, requiring an empty stomach for optimal effectiveness. Taking it at least 1 hour before meals ensures proper coating without food interference. Post-meal administration reduces efficacy, and documenting refusal is inappropriate without education.
Question 2 of 5
When caring for a client with diabetes insipidus who is receiving an antidiuretic hormone intranasally, which serum laboratory test is most important for the nurse to monitor?
Correct Answer: B
Rationale: Antidiuretic hormone (ADH) regulates water reabsorption, affecting serum osmolality. Monitoring osmolality assesses ADH therapy effectiveness in maintaining fluid balance in diabetes insipidus. Platelets, glucose, and calcium are not directly impacted by ADH or diabetes insipidus management.
Question 3 of 5
A client receives a prescription for penicillin G 1,000,000 units intramuscular (IM) daily. The medication is available in 1,200,000 units/2 mL syringe. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 1.7
Rationale: Calculate: (1,000,000 units ÷ 1,200,000 units) × 2 mL = 1.67 mL, rounded to 1.7 mL. This ensures the correct dose of penicillin G is administered intramuscularly.
Question 4 of 5
The home health nurse observes a client self-administering an epinephrine injection using an auto-injector pen. Which client action requires intervention by the nurse?
Correct Answer: C
Rationale: Epinephrine auto-injectors are single-use devices. Cleansing for reuse risks contamination or malfunction, requiring intervention. Holding the pen in place ensures full dose delivery, the thigh is the correct site, and injecting through clothing is acceptable in emergencies.
Question 5 of 5
The nurse is reviewing the laboratory results of a client who reports taking five times the recommended daily allowance of vitamins and minerals in a multivitamin form. Which finding indicates a possible vitamin D overdose? Reference Range: Bilirubin [0.3 to 1 mg/dL (5.1 to 17 μmol/L)] Calcium [9 to 10.5 mg/dL (2.3 to 2.6 mmol/L)] Sodium [136 to 145 mEq/L (136 to 145 mmol/L)] Blood Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]
Correct Answer: B
Rationale: Excessive vitamin D increases calcium absorption, causing hypercalcemia (12 mg/dL). This indicates a possible overdose, risking symptoms like nausea or confusion. Sodium, bilirubin, and glucose levels are unrelated to vitamin D toxicity.
