Correct Answer: B

Rationale: The correct answer is B: Objective data. Abnormal breath sounds, a productive cough, and cyanotic lips are all observable and measurable findings that can be verified by the nurse through assessment. Objective data refers to information that can be observed or measured, providing concrete evidence of the client's condition. In this case, the nurse directly perceives these physical signs during the assessment, making them objective data. Summary: - A: Subjective data involves the client's feelings or opinions, which are not directly observable by the nurse. - C: Secondary data are information obtained from other sources, not directly from the client. - D: Primary data are firsthand information collected directly from the client, but in this scenario, the findings are observable physical signs, making them objective data.

Correct Answer: C

Rationale: The normal range for intraocular pressure (IOP) is approximately 10-21 mm Hg. Choice C has an IOP of 11 mm Hg, falling within this normal range, making it the correct answer. Choices A, B, and D are outside the normal range, with A being too low and B and D being too high, indicating abnormal IOP levels. Choice A (8 mm Hg) is below the normal range, while choices B (25 mm Hg) and D (28 mm Hg) are above the normal range, therefore, they are incorrect answers.

Correct Answer: B

Rationale: The correct answer is B because inserting a mouth gag during a convulsive seizure can obstruct the airway and pose a choking hazard. Step-by-step rationale: A: Loosening clothing helps improve ventilation. C: Positioning on the side with head flexed forward prevents aspiration. D: Providing privacy is important for patient dignity and confidentiality. B is incorrect as it can be harmful.

Correct Answer: B

Rationale: The correct answer is B: Wash and inspect the feet daily. This is important for clients with diabetes mellitus to prevent complications like foot ulcers. Daily foot care helps detect any issues early. Choice A is incorrect as it is not recommended to use commercial preparations without medical advice. Choice C is incorrect as walking barefoot can increase the risk of injury and infection. Choice D is incorrect as cutting toenails by rounding edges can lead to ingrown toenails, which can be dangerous for clients with diabetes.

Correct Answer: C

Rationale: The correct answer is C: Hypoglycemia. In metabolic alkalosis, the blood pH is elevated due to an excess of bicarbonate. Hypoglycemia is not directly related to metabolic alkalosis but can be seen in other conditions like diabetes or fasting. Evaluating for hypocalcemia (A) is important as alkalosis can lead to decreased ionized calcium levels. Hypokalemia (B) is common in metabolic alkalosis due to potassium loss. Hypoxemia (D) is not directly related to metabolic alkalosis but can occur in severe cases due to respiratory compensation. Therefore, hypoglycemia is the least relevant in assessing metabolic alkalosis.
