A client has a prescription to take guaifenesin (Humibid) every 4 hours, as needed. The nurse determines that the client understands the most effective use of this medication if the client states that he or she will:
- A. Watch for irritability as a side effect.
- B. Take the tablet with a full glass of water.
- C. Take an extra dose if the cough is accompanied by fever.
- D. Crush the sustained-release tablet if immediate relief is needed.
Correct Answer: B
Rationale: Guaifenesin is an expectorant used to help loosen mucus and make coughs more productive. Taking it with a full glass of water helps decrease the viscosity of secretions, making it easier to expel mucus from the respiratory tract. It is important not to crush sustained-release tablets, as this can alter the intended release of the medication and lead to potential adverse effects.

- A. Increased risk of bleeding
- B. Decreased warfarin effectiveness
- C. Increased risk of thrombosis
- D. Decreased ciprofloxacin effectiveness

Therefore, the nurse should closely monitor the client's INR levels and watch for signs of bleeding such as bruising, petechiae, or black tarry stools.

- B. Take the daily dose at bedtime.
- C. Avoid changing brands of the medication without health care provider (HCP) approval.
- D. Avoid over-the-counter (OTC) cough and cold medications unless approved by the HCP.
Correct Answer: B
Rationale: The correct answer is B. Taking theophylline at bedtime is inappropriate because it can cause insomnia. The medication should be taken early in the morning to avoid disrupting sleep patterns. It is important to follow the healthcare provider's instructions regarding the timing of the medication to achieve optimal therapeutic effects.
The client has begun medication therapy with pancrelipase (Pancrease MT). The nurse evaluates that the medication is having the optimal intended benefit if which effect is observed?
- A. Weight loss
- B. Relief of heartburn
- C. Reduction of steatorrhea
- D. Absence of abdominal pain
Correct Answer: C
Rationale: Pancrelipase (Pancrease MT) is a pancreatic enzyme replacement therapy used to aid digestion in clients with pancreatic insufficiency. One of the key goals of pancrelipase therapy is to reduce the amount of undigested fat in the stool, known as steatorrhea. Therefore, the nurse should evaluate the effectiveness of pancrelipase by looking for a reduction in steatorrhea, indicating improved digestion and absorption of fats.
