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 teaching a client who will be discharged soon how to change a sterile dressing on the right leg. During the teaching session, the nurse notices redness, swelling and induration at the wound site. What do these signs suggest?
- A. Infection
- B. Evisceration
- C. Dehiscence
- D. Hemorrhage
Correct Answer: A
Rationale: The presence of redness, swelling, and induration at the wound site are classic signs of infection. Redness is caused by inflammation, swelling occurs due to fluid accumulation in response to infection, and induration refers to the hardening of the tissue, which is a result of the body's immune response. Infections can lead to delayed wound healing, increased pain, and other complications. It is essential to address these signs promptly to prevent further complications and promote healing.
An adult is to receive narcotic analgesics via patient controlled analgesia. The nurse is evaluating client's understanding of the procedure. Which of the following statements by the client indicates that she understand PCA?
- A. When I press this button the machine will always give me more medicine
- B. I will press the button whenever I feel pain
- C. I should press this button every hour so the pain doesn't come back
- D. With this machine I will experience no more pain
Correct Answer: B
Rationale: Statement B, "I will press the button whenever I feel pain," indicates that the client understands how to use the patient-controlled analgesia (PCA). PCA systems are designed to allow patients to self-administer a predetermined dose of pain medication when needed. This statement demonstrates the client's comprehension that it is appropriate to use the PCA when pain is experienced, navigating the misunderstanding that pressing the button will always give more medicine (A), that it should be pressed on a scheduled basis regardless of pain (C), or that it will completely eliminate pain (D).
The nurse notes that a child has lost 8 pounds after 4 days of hospitalization for acute glomerulonephritis. What is most likely the cause of the weight loss?
- A. Poor appetite
- B. Increased potassium intake
- C. Reduction of edema
- D. Restriction to bed rest
Correct Answer: C
Rationale: The child most likely lost 8 pounds due to a reduction of edema. Acute glomerulonephritis is a condition that can lead to significant fluid retention in the body, causing edema (swelling). When the child was hospitalized and received treatment, such as diuretics, to address the underlying cause of the edema, the excess fluid and weight would be lost. This reduction in edema is the most common reason for weight loss in this scenario, rather than poor appetite, increased potassium intake, or restriction to bed rest.

- C. HCO -: 30
- D. PaO : 96
Correct Answer: B
Rationale: pH: 7.35 - This pH value is within the normal range for a newborn and does not indicate acidosis or alkalosis.
