Which type of laxative causes peristalsis by irritating the bowel?
Stool softener
Saline/osmotic laxative
Stimulant laxative
Bulk-forming laxative
The Correct Answer is C
A) Stool softener:
Stool softeners, such as docusate sodium, work by adding moisture to the stool, making it softer and easier to pass. They do not directly stimulate bowel movements or peristalsis through irritation of the bowel lining.
B) Saline/osmotic laxative:
Saline or osmotic laxatives, such as magnesium hydroxide (milk of magnesia) and polyethylene glycol (PEG), work by drawing water into the intestines, which softens the stool and increases bowel motility. They do not primarily act by irritating the bowel lining.
C) Stimulant laxative.
Stimulant laxatives work by directly stimulating the nerves in the intestines, which increases the rhythmic contractions of the intestines (peristalsis) and promotes bowel movements. These medications irritate the bowel lining, leading to increased motility and expulsion of stool. Examples of stimulant laxatives include bisacodyl and senna.
D) Bulk-forming laxative:
Bulk-forming laxatives, such as psyllium and methylcellulose, work by increasing the bulk and water content of the stool, which stimulates bowel movements. They do not directly irritate the bowel lining to promote peristalsis. Instead, they absorb water and swell in the intestines, creating a larger, softer stool that is easier to pass.

Correct Answer is D
Explanation
A) Montelukast:
Montelukast is a leukotriene receptor antagonist used for the long-term control and prevention of asthma symptoms, but it is not typically used as a rescue medication to abort an ongoing asthma attack. Its onset of action is slower compared to short-acting beta agonists like albuterol.
B) Fluticasone:
Fluticasone is an inhaled corticosteroid medication used for the long-term control and management of asthma symptoms by reducing airway inflammation and preventing asthma exacerbations. It is not used as a rescue medication to abort an ongoing asthma attack but rather as a controller medication to prevent symptoms when used regularly over time.
C) Cromolyn:
Cromolyn is a mast cell stabilizer medication that is used for the prevention of asthma symptoms and exercise-induced bronchospasm. It is not typically used as a rescue medication to abort an ongoing asthma attack but rather as a controller medication to prevent symptoms when used regularly over time.
D) Albuterol.
Albuterol is a short-acting beta agonist bronchodilator commonly used as a rescue or reliever medication for acute asthma symptoms or to abort an ongoing asthma attack. It works quickly to relax the smooth muscles of the airways, leading to rapid bronchodilation and relief of symptoms such as wheezing, shortness of breath, and chest tightness. Albuterol is considered a first-line medication for relieving acute asthma symptoms and should be used as directed by a healthcare provider during an asthma exacerbation.
Correct Answer is D
Explanation
A. Hypotension: Norepinephrine is administered to treat hypotension, so monitoring for hypotension is not typically a concern while the patient is receiving this medication. In fact, hypotension is often the reason for administering norepinephrine in the first place.
B. Liver failure: Monitoring for signs of liver failure may be important in patients receiving certain medications, but it is not a specific consideration when administering norepinephrine. Norepinephrine primarily affects blood pressure regulation and does not typically have direct effects on liver function.
C. Bradycardia: While norepinephrine can increase blood pressure by constricting blood vessels, it may also cause reflex bradycardia (a decrease in heart rate) as a compensatory response. However, the primary concern with norepinephrine administration is hypertension, not bradycardia.
D. Hypertension
Norepinephrine (Levophed) is a vasopressor medication commonly used to treat hypotension and shock. It works by constricting blood vessels, which increases blood pressure. Therefore, when administering norepinephrine, the nurse should monitor the patient for hypertension, as the medication's intended effect is to raise blood pressure.
