Intravenous heparin therapy is prescribed for a client. While implementing this prescription, a nurse ensures while implementing this prescription, that which of the following medications is available on the nursing unit?
a. Protamine sulfate
b. Potassium chloride
c. Aminocaproic acid (amicar)
d. Vitamin K
a. Protamine Sulfate
Rationale: The antidote to heparin is protamine sulfate; it should be readily available for use if excessive bleeding or hemorrahge should occur. Vitamin K is an antidote for warfarin sodium. Amniocaproic acid is the antidote for thrombolytic therapy. Potassium chloride is administered for a potassium diet.
A client with peptic ulcer disease is taking ranitidine (Zantac). What is the expected outcome of this drug?
A. Heal the ulcer
B. Protect the ulcer surface from acids
C. Reduce acid concentration
D. Limit gastric acid secretion
D. Limit gastric acid secretion
Rationale: Ranitidine is a Histamine-2 receptor antagonist, meaning that is reduces gastric acid secretion. Anti-secretory or proton-pump inhibitors such as Prilosec, help ulcers heal quickly in 4-8 weeks. Cytoprotective drugs such as Carafate protect the ulcer surface against acid, bile and pepsin. Antacids are responsible for reducing acid concentration and helping to reduce symptoms.
3) Which of the following comments indicates that a client understands the nurse’s teaching about sertraline (Zoloft)?
a. “Zoloft will probably cause me to gain weight”
b. “This medication can cause delayed ejaculations”
c. “Dry mouth is a permanent side effect of Zoloft”
d. “I can take my medicine with St. John’s wort”
b. “This medication can cause delayed ejaculations”
Rationale: Sertraline is an SSRI which can cause decreased libido and sexual dysfunction. SSRI’s do not cause weight gain, but can cause decreased appetite and weight loss. Dry mouth is a possible side effect, but is temporary. St. John’s wort should not be taken with SSRI's because it can cause serotonin syndrome.
5) Which of the following therapeutic classes of drugs is used to treat tachycardia and angina in a client with pheochromocytoma?
a. Angiotensin- converting enzymes (ACE inhibitors)
b. Calcium channel blockers
c. Beta blockers
d. Diuretics
c. Beta blockers-
Rationale: A beta blocker is administered to block the cardiac-stimulating effects of epinephrine. ACE inhibitors and calcium channel blockers do not block sympathetic activity like beta blockers do and diuretics decrease fluid volume and peripheral resistance, not sympathetic activity.
Bethanechol (Urecholine) has been ordered for a client with gastroesophageal reflux disease (GERD). The nurse should assess the client for which of the following adverse effects.
A. Constipation
B. Urinary urgency
C. Hypertension
D. Dry oral mucosa
B. Urinary urgency
Rationale: Bethanecol (Urecholine), a cholinergic drug, may be used in GERD to increase lower esophageal sphincter pressure and facilitate gastric emptying. Cholinergic adverse effects may include urinary urgency, diarrhea, abdominal cramping, hypotension, and increased salivation.
