Correct Answer: B

Rationale: The correct answer is B: Aldosterone. Aldosterone is a hormone produced by the adrenal glands that helps regulate sodium and water balance in the body. It acts on the kidneys to increase reabsorption of sodium, leading to water retention and increased blood volume. This helps maintain blood pressure and electrolyte balance. A: Antidiuretic hormone (ADH) mainly acts on the kidneys to increase water reabsorption, not sodium retention. C: Thyroid hormone does not directly influence sodium retention. D: Insulin regulates blood sugar levels by promoting glucose uptake, it does not have a direct role in sodium retention.

Correct Answer: C

Rationale: The correct answer is C: Airway obstruction. Postoperatively, a nurse must assess for airway patency in a client with a nasal fracture to ensure proper breathing. Any swelling or bleeding in the nasal area can lead to airway obstruction, which is a critical concern that needs immediate intervention. Choices A, B, and D are incorrect because an allergic reaction, extreme sense of smell, and stridor are not typically associated with postoperative assessment of a nasal fracture. It is crucial to prioritize airway assessment to prevent any complications related to breathing difficulties in this situation.

Correct Answer: D

Rationale: The correct answer is D because developing a standard formal nursing diagnosis helps nurses focus on the scope of their practice. By identifying specific patient problems and their potential causes, nurses can provide appropriate interventions and evaluate patient outcomes effectively. This process enhances the quality of care delivery and promotes patient safety. A: This is incorrect because nursing diagnoses are not meant to be a language exclusive to nurses but rather a standardized way to communicate patient data. B: This is incorrect as nursing diagnoses are not about distinguishing roles but rather about identifying and addressing patient problems. C: This is incorrect as nursing diagnoses are based on evidence and critical thinking, not solely on intuition.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Metabolic acidosis is characterized by low pH and low plasma bicarbonate. 2. In this condition, there is an excess of acids or a loss of bicarbonate. 3. The kidneys are unable to adequately excrete acids or retain bicarbonate. 4. This leads to a decrease in bicarbonate levels and a decrease in pH. 5. Respiratory acidosis (A) is characterized by low pH and high CO2 levels. 6. Respiratory alkalosis (C) is characterized by high pH and low CO2 levels. 7. Metabolic alkalosis (D) is characterized by high pH and high bicarbonate levels. Summary: - Choice A is incorrect as it describes a condition with high CO2 levels. - Choice C is incorrect as it describes a condition with high pH. - Choice D is incorrect as it describes a condition with high bicarbonate levels. - Choice B is correct as it accurately describes the characteristics of a condition with low pH

Correct Answer: C

Rationale: The correct answer is C, which is to replace the foreskin over the head of the penis after washing. This is important to prevent any irritation or injury to the sensitive foreskin and glans. Leaving the foreskin retracted (A) can lead to discomfort and potential injury. Not retracting the foreskin (B) may not allow for proper cleaning. Using alcohol and a cotton swab (D) can be too harsh and irritating to the delicate tissues. Therefore, option C is the most appropriate and gentle approach to maintain proper hygiene and prevent any complications.
