1. One drug can alter the absorption of another drug. One drug increases intestinal motility. Which effect does this have on the second drug?
- A. None; absorption of the second drug is not affected.
- B. The increased gut motility decreases the absorption of the second drug.
- C. The absorption of the second drug cannot be predicted.
- D. Less of the second drug is absorbed.
Correct answer: D
Rationale: When one drug increases intestinal motility, it accelerates the movement of the second drug through the system. Since most oral medications are absorbed in the intestine, the faster transit time decreases the absorption of the second drug. Therefore, less of the second drug is absorbed. Choice A is incorrect because the increased gut motility does affect the absorption of the second drug. Choice C is incorrect as the effect of increased intestinal motility on drug absorption can be predicted based on pharmacokinetic principles. Choice B is incorrect as increased gut motility would not increase but decrease the absorption of the second drug.
2. The nurse is caring for a client with decreased cardiac output secondary to heart failure with fluid volume overload. The effects of diminished renal perfusion will have which physiologic response?
- A. Diuresis
- B. Increased fluid retention
- C. Elevated bicarbonate level
- D. Paroxysmal idiopathic narcosis
Correct answer: B
Rationale: When there is diminished renal perfusion due to decreased cardiac output, the kidneys receive less blood flow. This leads to a decrease in urine output and an increase in fluid retention, as the kidneys are not able to effectively filter and excrete excess fluid. Elevated bicarbonate level and paroxysmal idiopathic narcosis are not typically associated with diminished renal perfusion in heart failure. Therefore, the correct answer is 'Increased fluid retention.'
3. A client has been receiving cyanocobalamin (B12) injections for the past 6 weeks. Which laboratory finding indicates that the medication is having the desired effect?
- A. Neutrophil count of 60%
- B. Basophil count of 0.5%
- C. Monocyte count of 2%
- D. Reticulocyte count of 1%
Correct answer: D
Rationale: Cyanocobalamin is a B12 medication used for pernicious anemia. A reticulocyte count of 1% indicates the desired effect of the medication, as reticulocytes are immature red blood cells that increase in response to B12 therapy, improving anemia. Neutrophils, basophils, and monocytes are white blood cells and are not directly influenced by B12 injections, making them incorrect choices.
4. A 14-year-old boy has been admitted to a mental health unit for observation and treatment. The boy becomes agitated and starts yelling at nursing staff members. What should the nurse's first response be?
- A. Create an atmosphere of seclusion for the boy according to procedures.
- B. Remove other patients from the area for added safety.
- C. Ask the patient, "What is making you mad?"?
- D. Ask the patient, "Why are you behaving this way? Have you thought about what may help you calm down?"?
Correct answer: A
Rationale: In a situation where a patient is agitated and yelling, the first response should be to create an atmosphere of seclusion for the safety of the patient and others. Seclusion is a standard procedure to help manage aggressive behaviors and prevent harm. Options B, C, and D are not appropriate in this scenario. Removing other patients may not address the immediate safety concern, asking the patient what is making them mad can escalate the situation, and questioning why the patient is behaving that way may not help in managing the current agitation. Therefore, seclusion is the recommended course of action in this scenario to ensure the safety and well-being of all involved.
5. The drug of choice to decrease uric acid levels is:
- A. prednisone (Colisone)
- B. allopurinol (Zyloprim)
- C. indomethacin (Indocin)
- D. hydrochlorothiazide (HydroDiuril)
Correct answer: B
Rationale: The correct answer is allopurinol (Zyloprim) as it is a xanthine oxidase inhibitor that decreases uric acid formation. Allopurinol is commonly used to manage gout by lowering uric acid levels. Prednisone is a corticosteroid used to decrease inflammation, not to lower uric acid levels. Indomethacin is an analgesic, anti-inflammatory, and antipyretic agent, but it is not the drug of choice for lowering uric acid levels. Hydrochlorothiazide is a thiazide diuretic used to treat hypertension and edema, not to decrease uric acid levels.
