Extract:
Question 1 of 5
A nurse is preparing to administer 1,000 mL of lactated Ringer's IV over 6 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?
Correct Answer: A
Rationale: Using the formula (volume × drop factor) / time in minutes: (1000 mL × 10 gtt/mL) / 360 min = 27.78 gtt/min, rounded to 28 gtt/min.
Question 2 of 5
A client has prescriptions for albuterol (Proventil HFA) and salmeterol (Serevent). Which instruction should the nurse provide for this client?
Correct Answer: D
Rationale: Albuterol (short-acting) and salmeterol (long-acting) are both beta agonists, and taking them together increases the risk of side effects like tachycardia. They should be used as directed, typically not simultaneously.
Question 3 of 5
After taking the medication guaifenesin (Mucinex), the client complains of coughing up phlegm. What is the best response by the nurse?
Correct Answer: A
Rationale: Guaifenesin, an expectorant, loosens mucus, making coughing up phlegm a normal response. It is not an allergic reaction or indicative of new pathology.
Question 4 of 5
The nurse is teaching a client about digestion. Which statement reflects that the client understands the teaching?
Correct Answer: D
Rationale: Digestion is the breakdown of food into absorbable molecules. Other options describe cardiac output, peristalsis, or acid neutralization, which are not the full process of digestion.
Question 5 of 5
What is the earliest sign of shock that the nurse would monitor for during a routine assessment?
Correct Answer: A
Rationale: Restlessness is an early sign of shock, reflecting sympathetic nervous system activation due to decreased tissue perfusion. Pale skin, thirst, and nausea appear later.
