1. How is the stomach protected from damage by gastric acid?
- A. enzymes present in the stomach
- B. a protective bacteria in the stomach
- C. bicarbonate present in the stomach
- D. the mucus lining of the stomach
Correct answer: D
Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.
2. Which of the following conditions is not treated with Dexamethasone?
- A. Inflammation
- B. Asthma
- C. Addison’s disease
- D. Wilson’s disease
Correct answer: D
Rationale: Dexamethasone is not used to treat Wilson’s disease. It is a corticosteroid primarily used for conditions like inflammation, asthma, and Addison’s disease. Wilson’s disease is a genetic disorder involving copper accumulation and is treated with medications like chelating agents or zinc salts, not Dexamethasone.
3. What are the expected changes on an ECG for a patient with hypokalemia?
- A. Flattened T waves
- B. Prominent U waves
- C. ST elevation
- D. Wide QRS complexes
Correct answer: A
Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.
4. When conducting an initial feeding evaluation, the therapist asks the caregiver to bring the utensils, food, and high chair that they typically use. Which statement best reflects the therapist's reasoning for this?
- A. Using the child's actual materials will give the therapist an accurate picture
- B. The therapist wants to be sensitive to the child's culture
- C. The center has limited funds for food and materials
- D. The therapist would like to know if the caregiver can follow directions
Correct answer: A
Rationale: By having the caregiver bring the child's familiar utensils, food, and high chair, the therapist can observe the child's typical eating behaviors and challenges accurately. This provides valuable insights that help in tailoring appropriate interventions to address feeding issues effectively.
5. A nurse manager is preparing to review medication documentation with a group of newly licensed nurses. Which of the following statements should the nurse manager plan to include in the teaching?
- A. Use the complete name of the medication magnesium sulfate.
- B. Delete the space between the numerical dose and the unit of measure.
- C. Use the abbreviation SC when indicating a subcutaneous injection.
- D. Write the letter U when noting the dosage of insulin.
Correct answer: C
Rationale: The correct statement that the nurse manager should include in the teaching session is to use the abbreviation SC when indicating a subcutaneous injection. This is important for accurate and standardized medication documentation. Choice A is incorrect because using the complete name of medications is not always necessary and may lead to errors. Choice B is incorrect as spaces between dose and unit of measure are required for clarity and to avoid misinterpretation. Choice D is incorrect because the standard abbreviation for units should be used instead of the letter U to prevent confusion.
