Which time would be ideal for the LPN/LVN to collect a sputum specimen?

Correct Answer: B

Rationale: Morning is considered the ideal time for collecting a sputum specimen. Overnight, mucus accumulates in the respiratory tract because the patient is less active and not clearing their throat or coughing as much. This means that the mucus is more concentrated and has had time to build up, providing a more substantial and representative sample of what is in the lungs.

Correct Answer: C

Rationale: Deep breathing and coughing help to mobilize and clear respiratory secretions, promoting effective airway clearance and improved oxygenation.

Correct Answer: A

Rationale: In a client with anemia, the primary indication for oxygen therapy is to increase the oxygen-carrying capacity of the blood and improve tissue oxygenation.

Correct Answer: D

Rationale: A CPAP mask is the most appropriate oxygen delivery system for a client with sleep apnea who requires positive pressure ventilation. It delivers a continuous flow of pressurized air to keep the airways open during sleep.

Correct Answer: C

Rationale: NPPV devices, such as continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BIPAP), can cause dry mouth. Providing frequent oral care, such as mouth rinses and moisturizing agents, helps alleviate discomfort and prevent oral complications.
