Nursing Elites

1. Which of the following is the antidote for lead poisoning?

• A. Naloxone
• B. Nitrite
• C. CaEDTA
• D. Dialysis

Correct answer: C

Rationale: Calcium disodium ethylenediaminetetraacetic acid (CaEDTA) is the antidote for lead poisoning. CaEDTA works by chelating lead, forming a complex that is then excreted in the urine. It is used in chelation therapy to treat lead poisoning by reducing lead levels in the body.

2. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?

• A. These medications work by blocking HIV entry into cells.
• B. These medications work by weakening the cell wall of the HIV virus.
• C. These medications work by inhibiting enzymes to prevent HIV replication.
• D. These medications work by preventing protein synthesis within the HIV cell.

Correct answer: C

Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.

3. A client with active pulmonary tuberculosis (TB) is to be started on intravenous rifampin therapy. The client should be informed by the nurse that this medication can cause which of the following adverse effects?

• A. Constipation
• B. Black-colored stools
• C. Staining of teeth
• D. Body secretions turning a red-orange color

Correct answer: D

Rationale: The correct answer is D: Body secretions turning a red-orange color. Rifampin is known to cause body secretions, such as urine, sweat, tears, and sputum, to turn a harmless red-orange color. This is a common and expected side effect of rifampin therapy. Choices A, B, and C are incorrect. Constipation is not a common adverse effect of rifampin. Black-colored stools and staining of teeth are not associated with rifampin therapy. It is important for the nurse to educate the client about the harmless red-orange discoloration that may occur with this medication.

4. A healthcare professional is caring for a hospitalized client who has an activated partial thromboplastin time (aPTT) greater than 1.5 times the expected reference range. Which of the following blood products should the healthcare professional prepare to transfuse?

• A. Whole blood
• B. Platelets
• C. Fresh frozen plasma
• D. Packed red blood cells

Correct answer: C

Rationale: Fresh frozen plasma is the correct choice for a client with an elevated aPTT because it contains essential coagulation factors that can help correct coagulopathy and prevent bleeding. It is rich in clotting factors like fibrinogen, factors V and VIII, which are crucial in maintaining proper blood clotting function. Whole blood (Choice A) is not typically used to correct coagulopathy and is more suitable for situations requiring both volume and oxygen-carrying capacity. Platelets (Choice B) are indicated for thrombocytopenia, not for correcting coagulation factors. Packed red blood cells (Choice D) are used to increase oxygen-carrying capacity in cases of anemia, not for correcting coagulopathy.

5. A client has a prescription for furosemide. Which of the following instructions should the nurse include?

• A. Take furosemide in the morning.
• B. Eat a diet high in potassium.
• C. Avoid foods high in magnesium.
• D. Limit fluid intake to 1 liter per day.

Correct answer: B

Rationale: The correct instruction for a client taking furosemide is to eat a diet high in potassium. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Consuming foods rich in potassium can help maintain normal potassium levels in the body and counteract the potential side effect of furosemide. Choices A, C, and D are incorrect because taking furosemide in the morning does not specifically relate to its effectiveness or side effects, avoiding foods high in magnesium is not a primary concern when taking furosemide, and limiting fluid intake to 1 liter per day is not a general recommendation for individuals taking furosemide.
