Question

The nurse recognizes that adrenergic drugs cause relaxation of the bronchi and bronchodilation by stimulating which type of receptors?

Answer 1

Correct Answers:

Beta2 adrenergic

Rationale :

✅Beta2 adrenergic receptors are located in bronchial smooth muscle. ✅When stimulated, they relax airway muscles and cause bronchodilation, making breathing easier — especially during asthma or anaphylaxis. ✅Other receptor types do not produce this effect in the lungs.

Answer 2

Correct Answers:

"Drink a full glass of water with each dose."

Rationale :

Tetracyclines can irritate the GI tract. Taking them with a full glass of water minimizes esophageal irritation and helps absorption. Dairy products should be avoided as they reduce drug effectiveness.

Answer 3

Correct Answers:

Increased cardiac output

Rationale :

Adrenergic agonists stimulate beta1 receptors in the heart, increasing contractility and output — a key goal in cardiogenic shock. Improved perfusion confirms therapeutic response. Reduced urine output or anxiety are not primary indicators.

Answer 4

Correct Answers:

The client will demonstrate the proper technique of self-administering a metered-dose inhaler.

Rationale :

"Demonstrate" reflects a measurable, observable behavior — ideal for care planning. Understanding or knowing are vague and not quantifiable outcomes. Nursing plans should always include actionable evidence.

Answer 5

Correct Answers:

Abdominal pain of unknown origin

Rationale :

Laxatives can worsen undiagnosed abdominal conditions such as appendicitis or bowel obstruction. Using them without a confirmed diagnosis is dangerous. Chronic constipation or liver issues are not absolute contraindications.

Answer 6

Correct Answers:

Tell the client to blow her nose gently before the instillation.

Rationale :

Clearing the nasal passage improves medication absorption. Blowing the nose first ensures the drug reaches nasal mucosa. Other positions may not optimize delivery.

Answer 7

Correct Answers:

Request that the surgeon prescribe a different antibiotic.

Rationale :

Cephalexin is a cephalosporin, and clients with penicillin allergy may have cross-reactivity. The safest approach is to request an alternative. Administering the drug could trigger anaphylaxis.

Answer 8

Correct Answers:

Insert the suppository just beyond the internal sphincter
Lubricate dominant index finger

Rationale :

Suppositories must pass the internal sphincter to be effective. Lubrication ensures comfort and proper placement. Sterile gloves and supine position are unnecessary for this procedure.

Answer 9

Correct Answers:

Anticholinergics

Rationale :

Anticholinergics block parasympathetic activity, slowing gut motility. This reduces cramping and frequency of stools. Probiotics, absorbents, and lubricants do not directly affect muscle tone.

Answer 10

Correct Answers:

Obtain an order for a spacer device.

Rationale :

Spacers help deliver medication more effectively when inhaler coordination is poor. They are often recommended for children, older adults, and those with motor issues. Oral and peak flow options do not solve this specific issue.
