Nursing Elites

1. 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.

2. The nurse is working in a support group for clients with HIV. Which point is most important for the nurse to stress?

• A. They must inform household members of their condition.
• B. They must take their medications exactly as prescribed.
• C. They must abstain from substance use.
• D. They must avoid large crowds.

Correct answer: B

Rationale: The correct answer is that clients with HIV must take their medications exactly as prescribed. Antiretrovirals need to be taken as directed to prevent the development of drug-resistant strains and maintain treatment effectiveness. Missing doses can compromise the effectiveness of future treatments. Choice A, informing household members, is important for social support but not the most critical aspect of managing the condition. Choice C, abstaining from substance use, is important but not as crucial as medication adherence. Choice D, avoiding large crowds, is not directly related to HIV management as long as the individual's immune system is not significantly compromised.

3. A nurse and client are discussing the client's progress toward understanding his behavior under stress. This is typical of which phase in the therapeutic relationship?

• A. Pre-interaction
• B. Orientation
• C. Working
• D. Termination

Correct answer: C

Rationale: The correct answer is the working phase. During this phase, the nurse and client actively work together to explore alternative behaviors and techniques. Discussions in this phase focus on understanding the underlying meaning behind the behavior and implementing strategies for change. Pre-interaction (choice A) refers to the phase before the nurse and client first meet and establish a relationship. The orientation phase (choice B) involves introductions, setting goals, and establishing boundaries. Termination (choice D) is the phase where the therapeutic relationship concludes, and closure is achieved.

4. A nursing student caring for a 6-month-old infant is asked to collect a sample for urinalysis from the infant. How should the student collect the specimen?

• A. Catheterizing the infant using the smallest available Foley catheter
• B. Attaching a urinary collection device to the infant's perineum for collection
• C. Obtaining the specimen from the diaper by squeezing the diaper after the infant voids
• D. Noting the time of the next expected voiding and then preparing a specimen cup for the urine

Correct answer: B

Rationale: The correct method for collecting a urine sample from an infant for urinalysis is by attaching a urinary collection device to the infant's perineum. This device is a plastic bag with an adhesive opening that allows it to be secured to the perineum to collect urine. Catheterizing the infant with a Foley catheter should not be done unless specifically prescribed due to the risk of infection. Obtaining the specimen from the diaper by squeezing it after the infant voids may not provide an accurate sample for urinalysis. Trying to predict the time of the next voiding to prepare a specimen cup is not practical or reliable in ensuring an appropriate sample for urinalysis.

5. The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: A

Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.
