For each finding below, click to specify if the finding is consistent with the disease process of acute upper gastrointestinal bleed or acute lower gastrointestinal bleed. Each finding may support more than one disease process.
- A. Melena
- B. NSAID use
- C. Hematemesis
- D. History of diverticulosis
- E. History of Helicobacter pylori infection
Correct Answer:
Rationale: Upper gastrointestinal (Gl) bleeding can occur in the esophagus (eg, esophageal varices or in the stomach and duodenum
(eg, peptic ulcer). Findings associated with upper GI bleeding include the following:
• Melena (ie, dark, tarry stools) is due to the release of iron (heme) as blood passes through the entire GI tract and
hemoglobin becomes partially digested
• NSAID use increases the risk of peptic ulcer formation by inhibiting cyclooxygenase-1, an enzyme that helps protect the
stomach lining and promote platelet aggregation.
• Hematemesis (ie, vomiting blood) is due to the presence of blood in the upper GI tract (eg, esophagus, stomach,
duodenum); the blood usually has a coffee ground appearance due to digestion by gastric acid
• Helicobacter pylori infection increases gastric secretions, promoting peptic ulcer formation.
Lower Gl bleeding occurs in structures past the duodenum (eg, small and large intestine, rectum, anus) and is commonly
associated with inflammatory (eg, Crohn disease, ulcerative colitis, diverticulosis) or vascular (eg, hemorrhoids) conditions.
Diverticulosis is a condition where diverticula (ie, hollow outpouchings from the intestine) develop, usually in the large
intestine and occasionally in the small intestine. Diverticula weaken the intestinal wall and increase the risk for GI bleeding.

I can never get tuberculosis again once I finish treatment
- A. I should take the medications with antacids.
- B. I will notify my health care provider if my urine becomes orange.
- C. I will use additional contraception while taking rifampin
Correct Answer: D
Rationale: Rifampin is often used in the management of both latent and active tuberculosis (TB) but reduces the effectiveness of oral contraceptive
pills. Therefore, the client should be instructed to use additional methods of contraception during treatment and for 1 month following
the completion of treatment (Option 4).
The nurse is reinforcing home care teaching to the client. Which statement by the client requires the nurse to provide further instruction?
- A. I should ask family members to bring prepared meals to me." (13%)
- B. "I should eat small, frequent meals every 2-3 hours." (16%)
- C. I will avoid drinking fluids with my meals." (30%)
- D. I will eat hot soups to settle my stomach." (38%)
Correct Answer: D
Rationale: Self-management of hyperemesis gravidarum is an important component of discharge teaching. The goal of home care is to prevent nausea
and vomiting and promote appropriate nutritional intake and weight gain, which can support a healthy pregnancy.
Some triggers for nausea and vomiting include an empty or overly full stomach, strong food odors, and greasy or fatty foods. It is often
recommended that clients eat cold or bland foods due to the increased aromas associated with hot foods. Therefore, the nurse should
provide further teaching to this client who plans to eat hot soup because this may precipitate nausea (Option 4). The nurse can suggest
eating foods such as toast, crackers, nuts, or cold cereal.
The nurse receives prescriptions for medications to treat the client's hyperkalemia. For each medication, click to specify if the medication drives potassium from blood into cells, promotes potassium excretion, or stabilizes
myocardial cell membranes.
- A. Furosemide
- B. Albuterol
nebulizer
- C. Calcium gluconate
- D. Insulin and dextrose
Correct Answer:
Rationale: Several medications can rapidly correct a client's hyperkalemia by:
• Driving potassium from blood into cells: The serum potassium level can be temporarily lowered by administering an albuterol
nebulizer and IV insulin. Although albuterol and insulin are not usually administered for this purpose, they also shift potassium from the
extracellular space to the intracellular space. Because insulin transports both glucose and potassium into the cell, dextrose is
administered in combination with insulin to prevent hypoglycemia. Albuterol is not often used alone for hyperkalemia; it is often
administered with insulin and dextrose to improve the potassium-lowering effect.
• Promoting potassium excretion: Administration of loop diuretics (ie, potassium-wasting diuretics such as furosemide) will increase
the amount of potassium excreted into the urine at the loop of Henle and also treat the client's acute fluid volume overload.
• Stabilizing myocardial cell membranes: Administration of calcium gluconate antagonizes potassium and protects the myocardium
from potassium-induced dyshythmias by blocking potassium's effects and reducing myocardial irritability. Calcium gluconate does not
alter serum potassium levels and is usually indicated if there are ECG changes with hyperkalemia.
Complete the following sentence by choosing from the lists of options. The nurse suspects the client has ----------- and should implement ----------- precautions.
- A. Influenza
- B. Droplet
- C. Contact
- D. Standard
- E. Hepatitis A
Correct Answer: D,E
Rationale: Hepatitis A is an infection that leads to widespread inflammation of the liver. Transmission occurs through the fecal-oral route and is commo
in areas with overcrowding and poor sanitation. Outbreaks frequently result from contaminated water or food, and the condition is seen
primarily in resource-limited countries. Symptoms develop abruptly, initially including nausea, vomiting, anorexia, fever, and right upper
quadrant pain. A few days later, dark urine (bilirubinuria) and/or pale stools (lacking bilirubin pigment) may be seen. These are usually
followed by jaundice and pruritus. In addition, laboratory results show elevated liver function tests.
Hand hygiene, especially after toileting and before meals, is the most important intervention for reducing the risk of hepatitis A infection.
Therefore, for a client hospitalized with hepatitis A, standard precautions (ie, hand hygiene, disinfection of equipment and surfaces) must be
implemented to prevent transmission. Additional precautions (eg, disposable gown, gloves) should be used as needed (eg, during procedure
The nurse reinforces discharge teaching to the client after laser peripheral iridotomy. Which of the following client statements indicate an understanding of the teaching? Select all that apply.
- A. Gently pulling down my lower eyelid creates a pocket where I should administer the drops.
- B. I will apply pressure over the inner corner of my eye after administering each medication
- C. I will stop taking diphenhydramine because it can cause a glaucoma attack.
- D. I will wait 5 minutes between administering each eye drop medication.
- E. Touching my eye with the medication applicator may cause an infection.
Correct Answer: A,B,C,D,E
Rationale: Laser peripheral iridotomy is a surgical intervention for acute angle-closure glaucoma (ACG) that involves creating a small hole in the iris to
prevent the drainage pathway from closing and improve movement of aqueous humor into regular outflow channels. Ophthalmic alpha-
adrenergic agonists (eg, apraclonidine, brimonidine) are administered postoperatively to reduce aqueous humor production and prevent an
elevation in intraocular pressure.
Important considerations for the administration of ophthalmic drops include:
• Pulling the lower eyelid down by gently pressing on the lower orbital bone to expose the conjunctival sac (Option 1)
• Applying pressure over the inner corner of the eye (eg, lacrimal duct) after each medication to avoid systemic absorption (Option 2)
• Waiting at least 5 minutes before instilling a different medication into the same eye to allow absorption of the first medication and to
avoid overflow with multiple drops (Option 4)
• Holding the dropper ½*% in (1-2 cm) above the conjunctival sac to prevent contamination of the dropper and infection of the eye
(Option 5)
Clients should also be instructed to consult with their health care provider before taking over-the-counter medications (eg, decongestants,
anticholinergics, antihistamines) because a subsequent episode of acute ACG may be triggered by certain medications (Option 3).
