Nursing Elites

1. A healthcare professional reviews the blood gas results of a client in respiratory distress. The pH is 7.32, and the PCO2 is 50 mm Hg. Which of the following acid-base imbalances does the professional recognize in these findings?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, the pH is low (<7.35) and the PCO2 is increased (>45 mm Hg). These findings indicate that the client is experiencing respiratory acidosis, a condition where there is an excess of carbon dioxide in the blood due to inadequate ventilation, commonly seen in respiratory distress. Metabolic acidosis (Choice A) is characterized by a low pH and decreased bicarbonate levels, which is not the case in this scenario. Metabolic alkalosis (Choice B) is associated with a high pH and increased bicarbonate levels. Respiratory alkalosis (Choice D) is marked by a high pH and decreased PCO2, opposite to the values presented in the blood gas results of this client.

2. A client who underwent lobectomy 24 hours ago has not had any chest tube drainage for the past hour. What should the nurse do first?

• A. Contacts the physician
• B. Checks for kinks in the drainage system
• C. Checks the client’s blood pressure and heart rate
• D. Connects a new drainage system to the client’s chest tube

Correct answer: B

Rationale: When a chest tube is not draining, the nurse's initial action should be to check for kinks or clots in the chest drainage system. This step helps to ensure the patency of the system and allows for proper drainage. Checking the client's blood pressure and heart rate is important but not the priority when addressing a lack of chest tube drainage. Contacting the physician is warranted if signs of respiratory distress or mediastinal shift are observed after ruling out kinks or clots. Connecting a new drainage system is done when the fluid chamber is full, following a specific procedure to maintain a closed system and prevent complications.

3. A female patient who is allergic to penicillin will begin taking an antibiotic to treat a lower respiratory tract infection. The patient tells the nurse that she almost always develops a vaginal yeast infection when she takes antibiotics and that she will take fluconazole (Diflucan) with the antibiotic being prescribed. Which macrolide should the nurse question for this patient?

• A. Azithromycin (Zithromax)
• B. Clarithromycin (Biaxin)
• C. Erythromycin (E-Mycin)
• D. Fidaxomicin (Dificid)

Correct answer: C

Rationale: The nurse should question the prescription of erythromycin for this patient. When erythromycin is given concurrently with fluconazole, erythromycin blood concentration and the risk of sudden cardiac death increase. Therefore, it is not recommended to use erythromycin in combination with fluconazole for this patient. Azithromycin, clarithromycin, and fidaxomicin are alternative macrolide antibiotics that can be considered for this patient without the same risk of interactions when used with fluconazole.

4. The nurse is planning care for an older adult client who experienced a cerebrovascular accident several weeks ago. The client has expressive aphasia and often becomes frustrated with the nursing staff. Which intervention should the nurse implement?

• A. Teach the client the use of basic sign language
• B. Speak slowly to the client
• C. Encourage the client's use of picture charts
• D. Ask the client simple questions

Correct answer: C

Rationale: Encouraging the client's use of picture charts is the most appropriate intervention for a client with expressive aphasia. Picture charts provide visual cues that can aid in communication and reduce frustration for the client. This intervention can help the client express their needs and thoughts effectively. Teaching sign language (Choice A) may be challenging and not as practical in this situation as it may not address the specific communication barriers caused by expressive aphasia. Speaking slowly (Choice B) may not fully address the communication difficulties associated with expressive aphasia. Asking simple questions (Choice D) may not be effective as the client may have difficulty understanding and responding due to the nature of expressive aphasia.

5. Which of the following conditions is the most significant risk factor for the development of type 2 diabetes mellitus?

• A. Cigarette smoking.
• B. High-cholesterol diet.
• C. Obesity.
• D. Hypertension.

Correct answer: C

Rationale: Obesity is the most significant risk factor for developing type 2 diabetes mellitus due to its role in insulin resistance. Excess body fat, especially around the abdomen, leads to increased production of inflammatory markers and hormones that can cause insulin resistance. While cigarette smoking, high-cholesterol diet, and hypertension can contribute to health issues, they are not as directly linked to the development of type 2 diabetes mellitus as obesity.
