Question 1 of 5
Which deficiency in the mother has been primarily associated with neural tube defects in the fetus?
Correct Answer: B
Rationale: Folic acid deficiency in the mother has been primarily associated with neural tube defects in the fetus. Folic acid is crucial for the development of the neural tube in the early stages of pregnancy. Its deficiency can lead to neural tube defects, such as spina bifida or anencephaly. Iron deficiency is not directly related to neural tube defects but can cause other complications in pregnancy. Vitamin B12 is important for neurological function but is not the primary cause of neural tube defects. Vitamin E deficiency is not associated with neural tube defects in the fetus.
Question 2 of 5
When administering intravenous electrolyte solution, what precaution should the nurse take?
Correct Answer: C
Rationale: When administering intravenous electrolyte solutions, preventing the infiltration of calcium is crucial to avoid tissue necrosis and sloughing, making choice C the correct answer.
Choice A is revised to 'Infuse hypertonic solutions cautiously' because hypertonic solutions should be infused cautiously to prevent adverse effects.
Choice B is corrected to 'Mix no more than 60 mEq of potassium per liter of fluid' as exceeding this limit can lead to hyperkalemia.
Choice D is modified to 'Monitor the client's digitalis dosage for adjustments due to IV calcium' as it is essential to monitor the digitalis dosage for potential adjustments when IV calcium is administered; however, this choice is incorrect here as it inaccurately suggests adjusting the digitalis dosage due to IV calcium, which could lead to harmful effects.
Question 3 of 5
A nurse suspects a patient is developing Bell's Palsy. The nurse wants to test the function of cranial nerve VII. Which of the following would be the most appropriate testing procedures?
Correct Answer: B
Rationale: The facial nerve (VII) is responsible for motor function to the face and sensory function to the anterior two-thirds of the tongue.
Therefore, to appropriately test the function of cranial nerve VII, the most appropriate testing procedures involve assessing the taste sensation over the front of the tongue (sensory) and activation of the facial muscles (motor). Option B, 'Test the taste sensation over the front of the tongue and activation of the facial muscles,' is the correct answer.
Choices A, C, and D are incorrect because they do not involve the correct combination of sensory testing over the front of the tongue and motor activation of the facial muscles, which are key functions associated with cranial nerve VII.
Question 4 of 5
In the treatment of symptomatic bradycardia, which medication is most commonly recognized?
Correct Answer: D
Rationale: Atropine is the medication most commonly recognized for the treatment of symptomatic bradycardia because it increases the rate of conduction in the AV node, helping to alleviate bradycardia. Questran is a medication used to lower cholesterol levels and is not indicated for bradycardia. Digitalis, such as Digoxin, is used for heart failure and atrial fibrillation but not typically for bradycardia. Nitroglycerin is primarily used for angina and not bradycardia.
Question 5 of 5
The drug of choice to decrease uric acid levels is:
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.
