A client has a new order to take guaifenesin (Mucinex) every 4 hours as needed. The nurse giving medication instructions to the client tells the client to be sure to:

Take an extra dose if the cough is accompanied by fever.

Take the tablet with a full glass of water.

Crush the sustained-release tablet if immediate relief is needed.

Be aware of irritability as a side effect.

Answer and Explanation

The Correct Answer is B

A. Take an extra dose if the cough is accompanied by fever: Increasing the dosage without medical direction is unsafe and could lead to overdose or side effects. A fever with a cough may indicate infection and should prompt medical evaluation, not increased self-dosing.

B. Take the tablet with a full glass of water: Guaifenesin is an expectorant that helps loosen mucus in the airways. Taking it with a full glass of water enhances its effectiveness by promoting hydration, which is essential for thinning and mobilizing secretions.

C. Crush the sustained-release tablet if immediate relief is needed: Sustained-release tablets should never be crushed, as this destroys the time-release mechanism and can lead to rapid drug release and toxicity.

D. Be aware of irritability as a side effect: Irritability is not a common or expected side effect of guaifenesin. More typical side effects include nausea, vomiting, or dizziness. This instruction is misleading and not relevant for patient education.

Correct Answer is A

Explanation

A. Nose, then exhale more slowly through pursed lips:Pursed-lip breathing involves inhaling slowly through the nose and exhaling gently and slowly through pursed lips. This technique helps keep the airways open longer, promotes better gas exchange, and reduces shortness of breath.

B. Mouth, making her exhalation last three times longer than her inhalation:While prolonging exhalation is a goal of pursed-lip breathing, inhaling through the mouth does not support optimal airway conditioning.

C. Mouth, then exhale quickly through pursed lips:Exhaling quickly defeats the purpose of pursed-lip breathing, which is to slow down exhalation and prevent airway collapse. Inhaling through the mouth also bypasses natural airway filtering and warming.

D. Nose, making her inhalation last three times longer than her exhalation:The goal is to have a longer exhalation phase, not inhalation. Short inhalation and prolonged exhalation help reduce air trapping and improve oxygenation.

A. Nasal cannula B. Simple face mask C. Venturi mask D. Non-rebreather mask

Correct Answer is C

Explanation

A. Nasal cannula:The nasal cannula provides low-flow oxygen with variable concentrations depending on the patient's respiratory rate and tidal volume. It does not deliver a precise or consistent oxygen concentration.

B. Simple face mask:The simple face mask delivers moderate concentrations of oxygen, generally between 40–60%, but it lacks a mechanism for precise control. Oxygen delivery fluctuates based on the patient’s breathing pattern and flow rate.

C. Venturi mask:The Venturi mask is designed to deliver a specific and consistent concentration of oxygen by using color-coded adaptors that mix oxygen with room air at fixed ratios. This makes it ideal for patients who require accurate oxygen titration, such as those with COPD.

D. Non-rebreather mask:A non-rebreather mask delivers high concentrations of oxygen (up to 90–100%) but does not allow for fine control of the exact oxygen percentage. It is used in emergencies when high oxygen delivery is needed, not for precise regulation.
