Nursing Elites

1. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

2. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63mmHg, HCO3 23, and oxygenation saturation (SAO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

• A. tuberculosis (TB)
• B. pneumonia
• C. pleural effusion
• D. hypoxia

Correct answer: D

Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.

3. A healthcare provider is caring for a patient who has experienced burns to the right lower extremity. According to the Rule of Nines, which of the following percentages most accurately describes the severity of the injury?

• A. 36%
• B. 27%
• C. 18%
• D. 9%

Correct answer: C

Rationale: According to the Rule of Nines, the right lower extremity accounts for 18% of the total body surface area. The Rule of Nines divides the body into regions, each representing 9% or a multiple of 9%, allowing for a quick estimation of the extent of burns. In this case, the correct answer is 18% as it corresponds to the percentage allocated for each lower extremity. Choices A, B, and D are incorrect as they do not match the standard allocation for the right lower extremity in the Rule of Nines.

4. Melissa Smith came to the Emergency Department in the last week before her estimated date of confinement complaining of headaches, blurred vision, and vomiting. Suspecting PIH, the nurse should best respond to Melissa's complaints with which of the following statements?

• A. "The physician will probably want to admit you for observation."?
• B. "The physician will probably order bedrest at home."?
• C. "These are really dangerous signs."?
• D. "The physician will probably prescribe some medicine for you."?

Correct answer: B

Rationale: Pregnancy-induced hypertension (PIH) is a hypertensive disorder of pregnancy that can present after 20 weeks gestation. It is characterized by symptoms like edema, hypertension, and proteinuria, which can progress to conditions like pre-eclampsia and eclampsia. The best approach for a client with advanced PIH is rest, and home provides the most suitable environment for it. Hospitalization is not typically necessary for PIH unless there are severe complications. Medication alone is not the primary intervention for PIH; management often involves monitoring, rest, and close medical supervision. Therefore, advising bedrest at home is the most appropriate response to help manage PIH symptoms and prevent further complications, such as pre-eclampsia or eclampsia. The other options, like hospitalization for observation, emphasizing the danger of the signs without providing guidance, or assuming medication as the primary solution, are not in line with the standard management approach for PIH.

5. A client, age 28, was recently diagnosed with Hodgkin's disease. After staging, therapy is planned to include combination radiation therapy and systemic chemotherapy with MOPP"?nitrogen mustard, vincristine (Onconvin), prednisone, and procarbazine. In planning care for this client, the nurse should anticipate which of the following side effects to contribute to a sense of altered body image?

• A. Cushingoid appearance
• B. Alopecia
• C. Temporary or permanent sterility
• D. Pathologic fractures

Correct answer: B

Rationale: The correct answer is B: Alopecia. Chemotherapy drugs like vincristine can cause alopecia, which is hair loss. This side effect can significantly impact a patient's body image. While Cushingoid appearance (A) can be a side effect of long-term steroid use, temporary or permanent sterility (C) may affect a patient's future fertility but not necessarily alter body image. Pathologic fractures (D) are not common side effects of Hodgkin's disease or its treatment and do not directly contribute to a sense of altered body image in the same way as alopecia does.
