Nursing Elites

1. A healthcare professional is reviewing a patient's arterial blood gas values. Which of the following conditions apply under the following values? pH- 7.49 Bicarbonate ion 24 mEq/dl PaCO2 - 31 mmHg PaO2 - 52 mmHg FiO2 - 0.22

• A. respiratory acidosis
• B. respiratory alkalosis
• C. metabolic acidosis
• D. metabolic alkalosis

Correct answer: B

Rationale: The given blood gas values indicate respiratory alkalosis. A high pH and low PaCO2 level are consistent with respiratory alkalosis. In this scenario, no compensation for the alkalosis is noted, ruling out metabolic acidosis or alkalosis. Metabolic conditions would usually involve changes in bicarbonate levels, which remain within the normal range in this case.

2. While performing wound care to a donor skin graft site, the nurse notes some scabbing at the edges and a black collection of blood. What is the nurse's next action?

• A. Leave the scabbed area alone and apply extra ointment
• B. Notify the physician
• C. Gently remove the debris and re-dress the wound
• D. Apply skin softening lotion for 3 hours and then re-dress

Correct answer: C

Rationale: When the nurse notes scabbing at the edges and a black collection of blood, it indicates the presence of debris that needs to be addressed. Leaving the scabbed area alone and applying extra ointment may not address the underlying issue and could lead to complications. Notifying the physician is important in some cases, but immediate action is required to prevent infection in this situation. Gently removing the debris and re-dressing the wound is the correct course of action to promote healing and prevent complications.

3. Ten-year-old Jackie is admitted to the hospital with a medical diagnosis of Rheumatic Fever. She relates a history of 'a sore throat about a month ago.' Bed rest with bathroom privileges is prescribed. Which of the following nursing assessments should be given the highest priority when assessing Jackie's condition?

• A. her response to hospitalization
• B. the presence of a macular rash on her trunk
• C. her cardiac status
• D. the presence of polyarthritis and joint pain

Correct answer: C

Rationale: Monitoring Jackie's cardiac status is of the highest priority in a patient with rheumatic fever. Rheumatic fever can lead to permanent cardiac damage, making it crucial to closely monitor the heart. Assessing for signs of carditis, such as murmurs or other cardiac symptoms, is essential. The second priority is evaluating joint symptoms for the presence of polyarthritis and pain, which are common manifestations of rheumatic fever. While assessing Jackie's response to hospitalization is important for her emotional well-being, it is not the highest priority. The presence of a macular rash, although relevant, is not as high a priority as monitoring cardiac status or assessing joint symptoms.

4. Which of the following statements should the nurse use to best describe a very low-calorie diet (VLCD) to a client?

• A. "This diet can be used when there is close medical supervision."?
• B. "This is a long-term treatment measure that assists obese people who can't lose weight."?
• C. "The VLCD consists of solid food items that are pureed to facilitate digestion and absorption."?
• D. "A VLCD contains very little protein."?

Correct answer: A

Rationale: The correct answer is, "This diet can be used when there is close medical supervision."? Very low-calorie diets (VLCDs) are used in the clinical treatment of obesity under close medical supervision. The diet is low in calories, high in quality protein, and has a minimum of carbohydrates to spare protein and prevent ketosis. Choice B is incorrect because VLCDs are typically short-term interventions. Choice C is incorrect because VLCDs usually consist of nutritionally complete liquid formulations, not solid food items that are pureed. Choice D is incorrect because VLCDs actually contain a high quality of protein, although the overall caloric content is very low.

5. Which system is primarily affected by tuberculosis (Mycobacterium)?

• A. stomach (GI)
• B. heart (cardiac)
• C. lungs (respiratory)
• D. skin (integumentary)

Correct answer: C

Rationale: Tuberculosis, caused by Mycobacterium tuberculosis, primarily affects the respiratory system. This aerobic bacillus thrives in highly oxygenated body sites, such as the lungs, growing ends of bones, and the brain. The bacillus is airborne, making the lungs a common site for infection. Choices A, B, and D are incorrect as tuberculosis predominantly impacts the respiratory system and rarely involves the stomach, heart, or skin.
