In the nursing diagnosis 'Disturbed Self-Esteem related to presence of large scar over left side of face,' what part of the nursing diagnosis is 'presence of large scar over left side of face'?

Correct Answer: A

Rationale: The correct answer is A: Etiology. Etiology in a nursing diagnosis refers to the cause or contributing factors that lead to the identified problem. In this case, the presence of a large scar over the left side of the face is the underlying cause of the disturbed self-esteem. It directly influences the client's self-perception and self-worth. The problem (B) is the disturbed self-esteem itself, not the scar. Defining characteristics (C) are the signs and symptoms that support the nursing diagnosis. Client need (D) is a broader concept that encompasses the overall needs of the client, whereas etiology specifically focuses on the cause of the problem.

Correct Answer: B

Rationale: The correct answer is B: Communicating the client’s progress to the interdisciplinary team. During the evaluation phase, the nurse plays a crucial role in ensuring continuity of care by effectively communicating the client’s progress to the interdisciplinary team. This action allows for collaborative decision-making based on the latest information, promotes coordination of care, and ensures that all team members are informed and involved in the client's care plan. Rewriting the care plan (A) is important but may not be the most immediate action during the evaluation phase. Reassessing the client (C) is valuable for gathering additional data but may not directly contribute to continuity of care during this phase. Providing emotional support (D) is essential but may not specifically address continuity of care during evaluation.

Correct Answer: D

Rationale: Step-by-step rationale for choosing answer D as correct: 1. Acknowledges patient's withdrawn behavior 2. Demonstrates empathy and concern 3. Open-ended question allows patient to express feelings 4. Encourages patient to communicate concerns Summary: - Option A assumes a specific problem without patient input - Option B focuses on verbalization, not necessarily addressing underlying concerns - Option C makes assumptions about patient's worries without allowing him to express himself

Correct Answer: C

Rationale: The correct answer is C: 3.8 mL. To calculate the volume needed, first determine the concentration of the solution after reconstitution: 2.4 million units / 5,000,000 units = 0.48. Next, divide the desired dose by the concentration: 2.4 million units / 0.48 = 5 mL. Since the instructions state to dilute with 8 mL of sterile water, the total volume will be 13 mL. To find the volume of the powder to draw up, subtract the water volume from the total volume: 13 mL - 8 mL = 5 mL. Therefore, the nurse should draw up 5 mL of the reconstituted solution, which is equivalent to 3.8 mL of powder for injection. Incorrect choices: A, B, and D are incorrect because they do not consider the dilution factor of adding sterile water to the powder for injection. Option A is less than the

Correct Answer: D

Rationale: The correct answer is D, the bicarbonate-carbonic system. This buffer system is crucial in maintaining the body's pH balance. When CO2 combines with water in the blood, it forms carbonic acid, which dissociates into bicarbonate ions and hydrogen ions. Bicarbonate acts as a base, accepting excess hydrogen ions to prevent a decrease in pH. Hemoglobin and plasma proteins primarily function as transport molecules, not as buffer systems. Phosphate buffer system is present in intracellular fluids, not as commonly in the body. The bicarbonate-carbonic system is the most prevalent buffer system in the blood and plays a vital role in regulating blood pH.
