Nursing Elites

1. A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 0.5 mL
• B. 1 mL
• C. 1.5 mL
• D. 2 mL

Correct answer: A

Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg ÷ 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.

2. A home health nurse is planning to provide health promotion activities for a group of clients in the community. Which of the following activities is an example of the nurse promoting primary prevention?

• A. Educating clients about the recommended immunization schedule for adults
• B. Teaching clients how to manage chronic illnesses
• C. Providing counseling for depression
• D. Offering support groups for cancer survivors

Correct answer: A

Rationale: The correct answer is A: Educating clients about the recommended immunization schedule for adults. This activity falls under primary prevention, which aims to prevent the onset of illness or injury. Immunizations are a proactive measure to protect individuals from developing certain diseases. Choices B, C, and D involve managing chronic illnesses, providing counseling for mental health issues, and offering support for individuals who have already experienced cancer, respectively. These activities are more aligned with secondary or tertiary prevention, focusing on managing existing conditions or preventing complications in those already affected.

3. A client who is a Jehovah's Witness is admitted to the nursing unit. Which concern should the LPN have for planning care in terms of the client's beliefs?

• A. Autopsy of the body is prohibited.
• B. Blood transfusions are forbidden.
• C. Alcohol use in any form is not allowed.
• D. A vegetarian diet must be followed.

Correct answer: B

Rationale: The correct answer is B: 'Blood transfusions are forbidden.' Jehovah's Witnesses typically refuse blood transfusions due to their religious beliefs. This is crucial for the LPN to consider when planning the client's care to ensure that alternative treatments are explored. Choices A, C, and D are incorrect as they do not align with the specific beliefs and practices of Jehovah's Witnesses. Autopsy prohibition, alcohol use restrictions, and dietary preferences are not primary concerns related to the religious beliefs of Jehovah's Witnesses.

4. When developing a plan of care for a client with dementia, what should the LPN/LVN remember about confusion in the elderly?

• A. It is not a normal part of aging.
• B. It often follows relocation to new surroundings.
• C. It is primarily due to changes in the brain associated with the disease.
• D. It cannot be prevented or cured by adequate sleep alone.

Correct answer: B

Rationale: When caring for a client with dementia, it is crucial to understand that confusion often arises after relocating to new surroundings. This change can disrupt familiar routines and trigger increased disorientation and confusion. Choice A is correct because confusion in the elderly is not a normal part of aging. Choice C is incorrect because confusion in dementia is primarily due to changes in the brain associated with the disease, not just irreversible brain pathology. Choice D is incorrect because while adequate sleep is important for overall health, it alone cannot prevent or cure confusion associated with dementia.

5. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.
