,1. To help prevent VAP, the most important nursing action would be to:
A. Careful hand washing and use of gloves when suctioning
B. Keeping the head of the bed flat to reduce ICP
C. Performing routine oral suctioning every 2 hours
D. Administering broad-spectrum antibiotics prophylactically
Correct Answer: A
Rationale: Ventilator-Associated Pneumonia (VAP) is often caused by pathogens
, introduced during suctioning or other airway manipulations. Strict hand hygiene and
using sterile/clean gloves are the single most important infection control measures to
prevent VAP. Keeping the head of the bed elevated (not flat) to 30-45 degrees also helps
prevent VAP.
2. Measures that would be taken to tx a pt in DKA coma would not include which
response below?
A. Frequent monitoring of blood glucose levels
B. Intravenous fluid resuscitation with normal saline
C. Dextrose 50% IV infusion
D. Administration of regular insulin intravenously
Correct Answer: C
Rationale: In Diabetic Ketoacidosis (DKA), the blood glucose is dangerously high.
Dextrose 50% is a concentrated glucose solution used to treat hypoglycemia. In DKA,
insulin and IV fluids are given to lower blood glucose and correct dehydration. Dextrose
is only added to the IV fluids later, once the blood glucose drops to around 250 mg/dL,
to prevent hypoglycemia while continuing insulin.
3. Which of the following is not a manifestation of dig toxicity?
A. Flattening of t wave
B. ST depression
C. Bradycardia
D. Rapid AV conduction
Correct Answer: D
Rationale: Digoxin toxicity slows AV conduction (leading to bradycardia and heart block),
it does not cause rapid AV conduction. Classic ECG signs of digoxin toxicity include ST-
segment depression (scooping), T-wave flattening or inversion, and various arrhythmias
like bradycardia.
4. In dealing with a depressed pt during the first days post AMI the most appropriate
nursing action would be:
