1. 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.
2. 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.
3. The client is undergoing progressive ambulation on the third day after a myocardial infarction. Which clinical manifestation would indicate that the client should not be advanced to the next level?
- A. Facial flushing
- B. A complaint of chest heaviness
- C. Heart rate increase of 10 beats/min
- D. Systolic blood pressure increase of 10 mm Hg
Correct answer: B
Rationale: The correct answer is a complaint of chest heaviness. Onset of chest pain indicates myocardial ischemia, which can be life-threatening. Chest pain in a client post-myocardial infarction should be promptly evaluated, and the activity level should not be advanced. Choices A, C, and D are not the best options because facial flushing, a heart rate increase of 10 beats/min, and a systolic blood pressure increase of 10 mm Hg are not typical indicators of myocardial ischemia or necessarily contraindications for advancing activity levels in this context.
4. A patient has suffered a left CVA and developed severe hemiparesis resulting in a loss of mobility. The nurse notices on assessment that an area over the patient's left elbow appears as non-blanchable erythema, and the skin is intact. The nurse should score the patient as having which of the following?
- A. Stage I pressure ulcer
- B. Stage II pressure ulcer
- C. Stage III pressure ulcer
- D. Stage IV pressure ulcer
Correct answer: A
Rationale: Erythema with the skin intact is characteristic of a Stage I pressure ulcer. At this stage, the skin is not broken, but there is localized redness that does not blanch when pressed. Stage II pressure ulcers involve partial-thickness skin loss, Stage III pressure ulcers have full-thickness skin loss, and Stage IV pressure ulcers extend to deeper tissues, including muscle and bone. In this case, the non-blanchable erythema with intact skin aligns with the characteristics of a Stage I pressure ulcer.
5. Because of the possible nervous system side-effects that occur with isoniazid (Nydrazid) therapy, which supplementary nutritional agent would the nurse teach the client to take as a prophylaxis?
- A. Alpha tocopherol (vitamin E)
- B. Ascorbic acid (vitamin C)
- C. Calcitriol (vitamin D)
- D. Pyridoxine (vitamin B6)
Correct answer: D
Rationale: Pyridoxine is the correct choice in this scenario because it is used as a prophylaxis to prevent neuritis, a possible nervous system side-effect of isoniazid therapy. Neuritis is a condition that involves inflammation of the nerves and can be a side effect of isoniazid. Pyridoxine, also known as vitamin B6, helps prevent this side effect. Vitamin E (Alpha tocopherol), vitamin C (Ascorbic acid), and vitamin D (Calcitriol) do not specifically address the nervous system side-effects associated with isoniazid therapy, making them incorrect choices.
