Nursing Elites

1. A client is seen for testing to rule out Rocky Mountain Spotted Fever. Which of the following signs or symptoms is associated with this condition?

• A. Fever and rash
• B. Circumoral cyanosis
• C. Elevated glucose levels
• D. All of the above

Correct answer: A

Rationale: The correct answer is 'Fever and rash.' Rocky Mountain Spotted Fever (RMSP) is caused by the R. rickettsii pathogen, which damages blood vessels. Patients with RMSP typically present with fever, edema, and a rash that initially appears on the hands and feet before spreading across the body. The disease manifests following a tick bite. Choice A is correct as fever and rash are key indicators of RMSP. Circumoral cyanosis (choice B) is not typically associated with RMSP; it refers to a bluish discoloration around the mouth and is more indicative of oxygen deprivation. Elevated glucose levels (choice C) are not specific signs of RMSP. Therefore, choice D, 'All of the above,' is incorrect since only choice A, 'Fever and rash,' is associated with Rocky Mountain Spotted Fever.

2. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?

• A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
• B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
• C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
• D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%

Correct answer: D

Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.

3. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

4. A mother brings her 26-month-old to the well-child clinic. She expresses frustration and anger due to her child's constant saying 'no' and refusal to follow her directions. The nurse explains this is normal for his age, as negativism is attempting to meet which developmental need?

• A. Trust
• B. Initiative
• C. Independence
• D. Self-esteem

Correct answer: C

Rationale: In Erikson's theory of development, toddlers struggle to assert independence. They often use the word 'no' even when they mean yes. This stage is called autonomy versus shame and doubt. The child's behavior of saying 'no' and resisting directions reflects the developmental need for independence, not trust (option A), initiative (option B), or self-esteem (option D). Trust is typically associated with early infancy, initiative with preschool age, and self-esteem with later childhood and adolescence.

5. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.
