Beta-adrenergic agonists such as albuterol are given to Reggie, a child with asthma. Such drugs are administered primarily to do which of the following?
- A. Dilate the bronchioles
- B. Reduce secondary infections
- C. Decrease postnasal drip
- D. Reduce airway inflammation
Correct Answer: A
Rationale: Beta-adrenergic agonists like albuterol primarily work by relaxing and dilating the bronchioles, which are the smaller airways in the lungs. This leads to quick relief of asthma symptoms such as wheezing, shortness of breath, and chest tightness. By opening up the airways, these medications help improve airflow and make it easier for the individual to breathe. Beta-adrenergic agonists do not directly reduce airway inflammation, but they do provide immediate relief during an asthma attack by targeting bronchoconstriction.
The nurse is caring for a patient with HIV who has diarrhea. Which of the following would be most therapeutic to teach the patient to avoid in the diet to reduce diarrhea?
- A. Potassium-rich food
- B. Liquid nutritional supplements
- C. Raw fruits and vegetables
- D. Frozen products
Correct Answer: C
Rationale: Patients with HIV who have diarrhea should avoid consuming raw fruits and vegetables. Raw fruits and vegetables can be more difficult for the digestive system to break down, potentially worsening diarrhea. It is recommended to opt for cooked fruits and vegetables instead as they are easier to digest and less likely to irritate the gut. This can help reduce the frequency and severity of diarrhea in patients with HIV.

An elderly patient, Mr. Cruz is being cared for by nurse Bennie because of pulmonary embolism. Nurse Bennie would anticipate an order for immediate administration of:
- A. warfarin
- B. heparin
- C. dexamethazone
- D. protamine sulfate
Correct Answer: B
Rationale: In the scenario of an elderly patient like Mr. Cruz with suspected pulmonary embolism, the nurse would anticipate an order for the immediate administration of heparin. Heparin is an anticoagulant medication that works quickly to prevent the further development of blood clots. It is often used as the initial treatment for pulmonary embolism to prevent existing blood clots from getting larger and reduce the risk of new clots forming. Heparin is preferred over warfarin initially because it has a more rapid onset of action. Warfarin, which is a commonly used anticoagulant for longer-term management, takes several days to reach its full effect and requires monitoring of the prothrombin time (INR). Therefore, in Mr. Cruz's acute situation, heparin would be the most appropriate choice for immediate intervention to address the pulmonary embolism.
