Nursing Elites

1. Which of the following statements describes an active cellular membrane exchange process?

• A. Sodium moving out of cells and potassium moving into cells
• B. The movement of water from an area of low solute concentration to an area of high solute concentration
• C. The movement of insulin using a protein to travel across the cell membrane
• D. Oxygen moving across the pulmonary capillaries to an area of high carbon dioxide

Correct answer: A

Rationale: The correct answer is A. In active transport, energy is expended to move substances against their concentration gradient. Sodium moving out of cells and potassium moving into cells is an example of active transport because it requires energy to pump these ions across the cell membrane against their concentration gradients. Choices B, C, and D describe passive processes where substances move along their concentration gradients without the input of energy.

2. A patient is hospitalized due to nonadherence to an antitubercular drug treatment. Which of the following is most important for the nurse to do?

• A. Observe the patient taking the medications.
• B. Administer the medications parenterally.
• C. Instruct the family on the medication regimen.
• D. Count the number of tablets in the bottle daily.

Correct answer: A

Rationale: In this scenario, the most crucial action for the nurse to take is to observe the patient taking the medications. This ensures that the patient is actually consuming the prescribed antitubercular drugs, addressing the issue of nonadherence directly. Administering the medications parenterally (intravenously or intramuscularly) is not necessary unless there are specific medical reasons requiring this route of administration. Instructing the family on the medication regimen is important for support but may not directly address the patient's nonadherence. Counting the number of tablets in the bottle daily is not as effective as directly observing the patient taking the medications to ensure compliance.

3. A nurse is teaching a class about immune deficiencies, and a person from the audience asks which cells are affected by severe combined immune deficiency (SCID) syndrome, and the nurse answers:

• A. B cell deficits
• B. T cell deficits
• C. Complement deficits
• D. B and T cell deficits

Correct answer: D

Rationale: The correct answer is D: B and T cell deficits. Severe combined immune deficiency (SCID) syndrome affects both B and T cells, leading to a severe impairment in the immune system's ability to fight infections. Choice A (B cell deficits) is incorrect because SCID affects not only B cells but also T cells. Choice B (T cell deficits) is incorrect as SCID is characterized by deficits in both B and T cells. Choice C (Complement deficits) is incorrect as SCID primarily involves B and T cell deficiencies rather than complement deficiencies.

4. What causes atherosclerotic plaques to form in the body?

• A. Poor dietary habits
• B. Administration of statin medication
• C. Interruption of blood flow to the brain
• D. Injury to the endothelium of the coronary arteries

Correct answer: D

Rationale: Atherosclerotic plaques form in the body due to injury to the endothelium of the coronary arteries. When the endothelium is damaged, it triggers an inflammatory response that leads to the accumulation of fats, cholesterol, and other substances, forming plaques. These plaques can narrow the arteries, reducing blood flow and potentially leading to serious complications like heart attacks or strokes. Poor dietary habits (choice A) can contribute to the development of atherosclerosis by promoting the buildup of plaque-forming substances in the blood, but the direct cause is the injury to the endothelium. Administration of statin medication (choice B) is actually a treatment for high cholesterol and aims to reduce the risk of plaque formation. Interruption of blood flow to the brain (choice C) is more related to conditions like ischemic stroke rather than the primary cause of atherosclerotic plaque formation.

5. A patient is being educated on the administration of tinidazole (Tindamax). Which of the following indicates that the patient understands the administration of tinidazole?

• A. “I will report to the doctor if I have a slow heart rate.”
• B. “The medicine will leave a bitter or metallic taste in my mouth.”
• C. “I will report urinary urgency and incontinence.”
• D. “The medication is given in two doses every day.”

Correct answer: B

Rationale: The correct answer is B. Tinidazole (Tindamax) is known to cause a bitter or metallic taste in the mouth. This side effect is common and indicates that the patient understands the medication they are taking. Choices A, C, and D are incorrect because they do not specifically relate to the common side effects or administration details of tinidazole.
