1. What type of cells create exocrine secretions?

• A. alpha cells
• B. beta cells
• C. acinar cells
• D. plasma cells

Correct answer: C

Rationale: Acinar cells are responsible for creating exocrine secretions, such as enzymes and digestive juices. Alpha cells are found in the pancreas and are responsible for producing glucagon, beta cells produce insulin, and plasma cells are a type of white blood cell involved in immune responses. Therefore, the correct answer is acinar cells, as they specifically produce exocrine secretions.

2. The nurse observes a nursing assistant performing AM care for a client with a new leg cast. Which action by the assistant will the nurse intervene?

• A. Lifting the affected leg with the palms of the hand
• B. Covering the affected leg with a blanket to avoid chills
• C. Placing plastic over the groin prior to bathing
• D. Elevating the cased leg on two pillows

Correct answer: B

Rationale: The correct answer is covering the affected leg with a blanket to avoid chills. Covering the leg with a blanket can prevent the evaporation of heat from the new cast, which can lead to skin irritation or discomfort. Lifting the affected leg with the palms of the hand is appropriate as it helps in providing support and prevents unnecessary pressure on the cast. Placing plastic over the groin prior to bathing is also acceptable to protect the area from getting wet. Elevating the cased leg on two pillows helps reduce swelling and promotes circulation, making it a suitable action.

3. A patient's nurse taking a history notes complaints of SOB and weakness in the lower extremities. The patient has a history of hyperlipidemia and hypertension. Which of the following may be occurring?

• A. The patient may be developing CHF
• B. The patient may be having a MI
• C. The patient may be developing COPD
• D. The patient may be having an onset of PVD

Correct answer: B

Rationale: In this scenario, the patient's symptoms of shortness of breath (SOB) and weakness in the lower extremities, along with a history of hyperlipidemia and hypertension, are suggestive of a myocardial infarction (MI). It is important to note that MI can present with a variety of symptoms, including those affecting the respiratory system and muscle weakness. Choices A, C, and D are incorrect because the patient's symptoms are more indicative of a myocardial infarction rather than congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), or peripheral vascular disease (PVD).

4. Which medication should the nurse withhold if the client's blood pressure is 88/50?

• A. Rosuvastatin (Crestor)
• B. Enalapril (Vasotec)
• C. Digoxin (Lanoxin)
• D. Clopidogrel (Plavix)

Correct answer: B

Rationale: Enalapril (Vasotec) is the correct answer. It is an angiotensin-converting enzyme (ACE) inhibitor that can further lower blood pressure. Given that the client's blood pressure is already low at 88/50, administering Enalapril could exacerbate hypotension and compromise perfusion to vital organs. Rosuvastatin (Crestor), Digoxin (Lanoxin), and Clopidogrel (Plavix) are not contraindicated in the context of low blood pressure and may be administered safely.

5. 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.
