Nursing Elites

1. The client has an order for 0.45 mg of Diltiazem. The medication vial has a concentration of 3 mg/mL. How many mL of the drug should be administered?

• A. 0.15 mL
• B. 6.6 mL
• C. 1.5 mL
• D. 0.65 mL

Correct answer: 0.15 mL

Rationale: To calculate the amount of drug to be administered, divide the ordered dose by the concentration of the medication in the vial. In this case, 0.45 mg ÷ 3 mg/mL = 0.15 mL. Therefore, the correct answer is 0.15 mL. Choice B (6.6 mL) is incorrect as it does not result from the correct calculation. Choice C (1.5 mL) is incorrect as it is not the result of dividing the ordered dose by the concentration. Choice D (0.65 mL) is incorrect as it is not the accurate calculation based on the provided information.

2. An LPN is reviewing medication lists for several clients recently admitted to the hospital. Which of the following scenarios would be least concerning?

• A. A client taking allopurinol for gout states they have been taking black cohosh to help with post-menopausal symptoms.
• B. A client has an order for warfarin and states they have been taking Ginkgo biloba to improve their memory.
• C. A client taking Lipitor states they have been taking ginseng for an energy boost.
• D. A client has a prescription for an SSRI and states they have been taking St. John’s wort to also help with their depression.

Correct answer: A client taking Lipitor states they have been taking ginseng for an energy boost.

Rationale: The least concerning scenario is when a client taking Lipitor states they have been taking ginseng for an energy boost. While ginseng may cause an increased risk of bleeding, it should not interact with Lipitor. On the other hand, St. John’s wort should not be taken with an SSRI as it may cause serotonin syndrome, posing a more serious concern. Black cohosh should not be taken with allopurinol as they can both cause hepatotoxicity, especially in combination. Ginkgo biloba should not be taken with warfarin as it causes an increased risk of bleeding, making it a more concerning scenario compared to the client taking Lipitor and ginseng.

3. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client’s cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: The client has a normal cardiac output.

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

4. A school nurse provides information to the parents of school-age children regarding appropriate dental care. The nurse tells the parents that their children should perform which action?

• A. Brush and floss their teeth after meals and at bedtime
• B. Brush their teeth every morning and at bedtime and floss the teeth once a day, preferably at bedtime
• C. Brush their teeth every morning and at bedtime
• D. Brush and floss their teeth every morning and at bedtime

Correct answer: Brush and floss their teeth after meals and at bedtime

Rationale: School-age children are capable of taking responsibility for their own dental hygiene. Establishing good oral health habits during childhood can lead to a lifetime of cavity prevention. The nurse advises the parents that their children should brush with fluoride toothpaste and floss between their teeth after meals and before bedtime. This routine helps maintain good oral health and teaches children the importance of dental care. Choice A is the correct answer as it emphasizes both brushing and flossing after meals and at bedtime, which are crucial for effective dental care. Choices B, C, and D are incorrect as they do not stress the significance of both brushing and flossing after meals, which is essential for proper oral hygiene.

5. During a routine health screening for a 1-year-old child, what is the most critical topic for the nurse to discuss with the parents?

• A. the potential hazards of accidents
• B. appropriate nutrition now that the child has been weaned from breastfeeding
• C. toilet training
• D. how to purchase appropriate shoes now that the child is walking

Correct answer: the potential hazards of accidents

Rationale: During a routine health screening for a 1-year-old child, the most critical topic for the nurse to discuss with the parents is the potential hazards of accidents. Accidents are the primary source of injury in children and can be life-threatening. Discussions about appropriate nutrition should have been addressed during the weaning process, while the purchase of appropriate shoes is important but not life-threatening. Toilet training typically begins around 2 years of age, so 1 year of age is too early to discuss it. Therefore, the focus should be on educating parents about accident prevention to ensure the child's safety and well-being.
