1. Metformin (Glucophage) is administered to clients with type II diabetes mellitus. Metformin is an example of:
- A. an antihyperglycemic agent.
- B. a hypoglycemic agent.
- C. an insulin analogue.
- D. a pancreatic alpha cell stimulant
Correct answer: A
Rationale: Metformin is classified as an antihyperglycemic agent because it works by reducing hepatic glucose output and decreasing glucose absorption from the gut, thereby preventing hyperglycemia. Choice B, a hypoglycemic agent, is incorrect as hypoglycemic agents stimulate insulin production, which is not the mechanism of action of metformin. Choice C, an insulin analogue, is incorrect as metformin is not a type of insulin but a distinct medication. Choice D, a pancreatic alpha cell stimulant, is incorrect as metformin does not stimulate any pancreatic cells, but rather acts on the liver and gut to lower blood sugar levels.
2. Which of the following is an inappropriate item to include in planning care for a severely neutropenic client?
- A. Transfuse neutrophils (granulocytes) to prevent infection.
- B. Exclude raw vegetables from the diet.
- C. Avoid administering rectal suppositories.
- D. Prohibit vases of fresh flowers and plants in the client's room.
Correct answer: A
Rationale: The correct answer is to transfuse neutrophils (granulocytes) to prevent infection. Granulocyte transfusion is not routinely indicated to prevent infection in neutropenic clients. While neutrophils are essential in fighting infections and are beneficial in selected populations of infected, severely granulocytopenic clients who do not respond to antibiotics and are expected to experience prolonged suppression of granulocyte production, routine granulocyte transfusion is not recommended. Choices B, C, and D are appropriate interventions for a severely neutropenic client. Prohibiting fresh flowers and plants helps reduce the risk of exposure to environmental pathogens. Avoiding rectal suppositories minimizes the risk of introducing harmful bacteria. Excluding raw vegetables from the diet reduces the likelihood of foodborne infections.
3. Which microorganism is most commonly associated with gastritis?
- A. Syphilis
- B. Cytomegalovirus
- C. H. pylori
- D. Mycobacterium
Correct answer: C
Rationale: H. pylori is the most common microorganism associated with gastritis, present in over 80% of cases. While syphilis, cytomegalovirus, and mycobacterium can also cause gastritis, they are much less prevalent compared to H. pylori. Therefore, the correct answer is H. pylori.
4. Is head lag expected to be resolved by 4 months of age? Continuing head lag at 6 months of age may indicate?
- A. Dizziness and orthostatic hypotension.
- B. Nausea, vomiting, diarrhea, or constipation, and stomach cramps.
- C. Drowsiness, lethargy, and fatigue.
- D. Neuropathy and tingling in the extremities.
Correct answer: B
Rationale: Head lag is a developmental milestone that should be resolved by 4 months of age. Continuing head lag at 6 months of age may indicate potential developmental delays or muscle weakness. The correct answer, 'Nausea, vomiting, diarrhea, or constipation, and stomach cramps,' reflects symptoms that could be associated with developmental delays or underlying health conditions. Dizziness and orthostatic hypotension (Choice A) are unlikely to be directly related to head lag. Choices C and D present symptoms that are unrelated to the issue of continued head lag at 6 months of age.
5. Herbal therapy has several indications for use. Primarily, herbal therapy is:
- A. used to treat many common complaints and diseases.
- B. used to promote certain types of low-carb diets.
- C. used as an adjunct to medications.
- D. used to create a diet without salt and carbohydrates.
Correct answer: A
Rationale: The correct answer is A: 'used to treat many common complaints and diseases.' Herbal therapy is commonly used to address a variety of health issues and ailments by utilizing natural remedies derived from plants. Choices B, C, and D are incorrect because herbal therapy's primary purpose is not to promote specific diets, act as an adjunct to medications, or create specific dietary restrictions, but rather to provide alternative treatment options for various health conditions.
