The nurse is observing a client self-administer two medications that are in a crushable pill form through their G tube. Which of the following would indicate a need for further instruction?
- A. The client flushes the G-tube before administering the medications, in between the two medications, and after the medications.
- B. The client states they will remain in the Semi-Fowler's position for 30 minutes following administration of the medications.
- C. The client mixes their medications with their tube-feeding formula.
- D. The client mixes each medication separately in warm water.
Correct Answer: C
Rationale: Medication should not be mixed with tube-feeding formula or other medications. The G-tube should be flushed before, between, and after the medications, and the client should remain in the Semi-Fowler's position for at least 30 minutes after medications are administered.
The 5-year-old is receiving an IV infusion of D5 with 0.45 NaCl at 100 mL/hr. Which assessment findings suggest excessive parenteral fluid intake? Select all that apply.
- A. Dyspnea
- B. Lethargy
- C. Gastric distention
- D. Crackles in lung bases
- E. Temperature of 102°F (38.9°C)
Correct Answer: A,B,D
Rationale: A: Dyspnea indicates fluid volume overload and occurs from fluid rapidly shifting between the intracellular and extracellular compartments. B: Lethargy and change in level of consciousness can occur from fluid shifting in brain cells. C: Gastric distention can occur from excessive oral (not IV) fluid intake or infection. D: Crackles indicate fluid volume overload and occur from fluid rapidly shifting into the alveoli. E: An elevated temperature is a sign of fluid volume deficit, not excess.
A physician orders a serum creatinine for a hospitalized client. The nurse should explain to the client and his family that this test:
- A. is normal if the level is 4.0 to 5.5 mg/dl.
- B. can be elevated with increased protein intake.
- C. is a better indicator of renal function than the BUN.
- D. reflects the fluid volume status of a person.
Correct Answer: C
Rationale: A serum creatinine level should be 0.7 to 1.5 mg/dl, and it does not vary with increased protein intake, so it is a better indicator of renal function than the BUN, which can be affected by diet and hydration status.
The nurse is reviewing the chart illustrated of the client diagnosed with stage III HF. Which conclusion should the nurse make?
- A. The medications should be administered as prescribed.
- B. The client may be experiencing toxicity from digoxin.
- C. Hyperkalemia likely caused the client's cardiac dysrhythmias.
- D. Seeing halos can result from the atrial fibrillation or anticoagulants.
Correct Answer: B
Rationale: A: The digoxin should be withheld and not given until a serum digoxin level is determined. B: Signs of digoxin (Lanoxin) toxicity include seeing yellow halos around objects and dysrhythmias. The furosemide (Lasix) diuretic increases urinary excretion of potassium and can cause hypokalemia. Hypokalemia can contribute to both cardiac dysrhythmias and digoxin toxicity. C: A serum potassium level of 2.9 mEq/L indicates hypokalemia, not hyperkalemia. D: The yellow vision is a characteristic sign of digoxin toxicity and is not a sign of cerebral damage from an infarct due to atrial fibrillation or bleeding from the anticoagulants.
The hospitalized adult is having difficulty falling and staying asleep. The nurse consults standing orders, which have medications included in the table illustrated. Which hypnotic medication should the nurse administer to effectively help the client sleep soundly throughout the night?
- A. Zaleplon
- B. Triazolam
- C. Flurazepam
- D. Eszopiclone
Correct Answer: B
Rationale: Triazolam (Halcion) has a later peak and longer duration, helping the client fall and stay asleep longer.
