Nursing Elites

1. 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: C

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.

2. The nurse is observing a client self-administer two crushable medications through their G-tube. Which of the following would indicate a need for further instruction?

• A. The client flushes the G-tube before administering the medications, in between the two medications, and after the medications.
• B. The client states they will remain in the Semi-Fowler's position for 30 minutes following the administration of the medications.
• C. The client mixes each medication separately in warm water.
• D. The client mixes their medications with their tube-feeding formula.

Correct answer: D

Rationale: The correct answer is that the client mixes their medications with their tube-feeding formula. Medications should not be mixed with tube-feeding formula or other medications as it may alter their effectiveness. The G-tube should be flushed before, between, and after the medications to prevent clogging and ensure proper administration. The client should remain in the Semi-Fowler's position for at least 30 minutes after medication administration to prevent reflux. Choice B is correct as it aligns with the proper post-administration positioning. Choices A and C are incorrect as flushing the G-tube before, between, and after medications, and mixing each medication separately in warm water are appropriate procedures that do not indicate a need for further instruction.

3. A hepatitis B screen is performed on a pregnant client, and the results indicate the presence of antigens in the client's blood. On the basis of this finding, the nurse makes which determination?

• A. Hepatitis immune globulin and vaccine will be administered to the newborn infant soon after birth
• B. The results are negative.
• C. The results indicate that the mother does not have hepatitis B
• D. The client needs to receive the hepatitis B series of vaccines.

Correct answer: A

Rationale: A hepatitis B screen is performed to identify antigens in maternal blood. If antigens are present, it indicates that the mother is a carrier, and the newborn will need to receive hepatitis immune globulin and vaccine soon after birth to prevent transmission. Therefore, choice A is correct. Choices B and C are incorrect because the presence of antigens indicates a positive result, not a negative one or the absence of hepatitis B in the mother. Choice D is incorrect as it suggests the client needs to receive the hepatitis B series of vaccines, which is not the immediate action required when antigens are found in the maternal blood.

4. A mother has come to the pediatric clinic concerned about the recent outbreak of West Nile Virus. The ages of her children are 5, 7, and 10. The mother has asked the nurse what she can do to prevent her children from contracting this illness. Which piece of information is best to provide the mother with?

• A. The children should wear long sleeves and long pants while outside.
• B. Apply insect repellent containing DEET when the children are outside.
• C. Remove standing water from the property.
• D. All of the above.

Correct answer: D

Rationale: The best advice to provide to the mother is 'All of the above.' It is recommended that the children wear insect repellent containing DEET and long-sleeved shirts and long pants when they are outside. This helps in preventing mosquito bites, which can transmit the West Nile Virus. Additionally, removing standing water from areas where the children play can help decrease the number of breeding mosquitoes, reducing the risk of contracting the virus. These methods work in combination to provide effective prevention against the West Nile Virus, making 'All of the above' the correct choice. Choices A, B, and C individually address important prevention measures, but a combination of all three strategies is the most comprehensive approach to protect the children from contracting the illness.

5. The LPN is caring for a client taking Lipitor (Atorvastatin). Which of these statements would indicate that the client may need reinforced teaching?

• A. "I take my Lipitor with a glass of milk after my breakfast."?
• B. "I take my Lipitor and wait 30 minutes before taking my other medications."?
• C. "I take my Lipitor 30 minutes after I eat something."?
• D. "I take my Lipitor and my other morning medications with my grapefruit juice at breakfast."?

Correct answer: D

Rationale: The correct answer is, 'I take my Lipitor and my other morning medications with my grapefruit juice at breakfast.' This statement indicates a need for reinforced teaching because grapefruit juice should be avoided when taking Lipitor. Grapefruit juice blocks the enzymes needed to break down the drug, which leads to excessive amounts of the drug in the body. Choices A, B, and C show appropriate timing and administration of Lipitor, whereas choice D poses a potential risk due to the interaction between grapefruit juice and Lipitor.
