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

At bedtime

In the morning

After meals

After start of antibiotics

Answer and Explanation

The Correct Answer is B

B. 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.
A. Collecting a sputum specimen at bedtime is generally not ideal. By the end of the day, the patient’s respiratory tract might have cleared some of the accumulated mucus naturally through coughing or other activities.
C. Collecting a sputum specimen after meals is not recommended. Eating can introduce food particles and bacteria from the mouth into the sputum, contaminating the sample.
D. Starting antibiotics before collecting a sputum specimen can alter the bacterial flora present in the respiratory tract. This can lead to a false-negative result or an inaccurate representation of the pathogens causing the infection.

Correct Answer is A

Explanation

A. Sucralfate works by forming a protective barrier over the ulcer site. It adheres to the ulcer, shielding it from the harmful effects of gastric acid, pepsin, and bile salts. This protection allows the ulcer to heal by preventing further irritation and damage.
B. Medications that prevent gastric acid secretion are typically proton pump inhibitors (PPIs) or H2 receptor antagonists. Sucralfate does not reduce or inhibit the production of gastric acid; instead, it protects the ulcer from the acid already present.
C. Antacids are the type of medication that neutralize gastric acid. Sucralfate does not neutralize acid; it acts locally at the ulcer site to create a protective coating.
D. Antibiotics are used to kill Helicobacter pylori, the bacteria often responsible for causing peptic ulcers. Sucralfate does not have antibacterial properties and does not target or eliminate bacteria.

RR: 24 breaths/min; rapid, deep - The respiratory rate has decreased from 26 breaths/min, indicating less rapid breathing.

BP: 94/56 mm Hg - While the blood pressure remains relatively low, there is a slight improvement compared to the previous reading.

Glucose 460 mg/dl - The glucose level has decreased from 525 mg/dL and 530 mg/dL in previous readings. While still elevated, this indicates some improvement in hyperglycemia.
