Correct Answer: D

Rationale: The correct answer is D. Asking about seeing halos around lights is relevant to assessing the patient's eye health as it could indicate conditions like glaucoma or cataracts. Upper respiratory infections (A), riding in a car (B), and scuba diving (C) are not directly related to eye health assessment. By focusing on symptoms directly related to the eyes, the nurse can gather relevant information for a more accurate assessment.

Correct Answer: A

Rationale: The correct answer is A: Trousseau's sign. A serum calcium level of 7.2mg/dl indicates hypocalcemia. Trousseau's sign is a clinical manifestation of hypocalcemia, characterized by carpal spasm induced by inflating a blood pressure cuff above systolic pressure. This occurs due to increased neuromuscular excitability from low calcium levels. Hegar's sign (B) is associated with pregnancy, Homan's sign (C) is a clinical test for deep vein thrombosis, and Goodell's sign (D) is a softening of the cervix during pregnancy. These signs are not relevant to a client with hypocalcemia.

Correct Answer: C

Rationale: The correct answer is C: Developing nursing diagnoses before completing the database. This is incorrect because developing nursing diagnoses should be based on a comprehensive assessment and analysis of the patient's data. By developing nursing diagnoses before completing the database, the new nurse may overlook important information that could impact the accuracy of the diagnosis and subsequent care plan. Choice A (intravenous antibiotics) is incorrect because assigning a nursing diagnosis of Risk for infection for a patient on IV antibiotics is a common and appropriate practice given the increased risk of infection associated with invasive procedures. Choice B (Completing an interview and physical examination before adding a nursing diagnosis) is incorrect because nursing diagnoses should be developed based on the data collected during the assessment process, which includes the interview and physical examination. It is not necessary to complete the entire assessment before assigning a nursing diagnosis. Choice D (Including cultural and religious preferences in the database) is incorrect because while it is important to consider cultural and religious preferences in care planning, this does not directly relate to the

Correct Answer: A

Rationale: The correct answer is A: 11mEq/L. In renal failure, the kidneys are unable to excrete excess magnesium, leading to hypermagnesemia. The patient's symptoms of stomach distress and ingesting antacids suggest magnesium intake. A Mg level of 11mEq/L aligns with symptoms like flushed face and weakness. Choices B, C, and D are too low for hypermagnesemia symptoms and would not explain the patient's presentation.

Correct Answer: A

Rationale: The correct answer is A because the drug should be resumed when the WBC count falls to 5,000mm3 to ensure the client's safety and efficacy of treatment. This criterion indicates that the client's immune system has recovered sufficiently to tolerate the drug. Choices B, C, and D are incorrect because they do not directly correlate with the client's immune system recovery, which is crucial for drug tolerance. Choice B focuses on the rise in WBC count, not the fall to a specific level. Choice C is related to a cosmetic side effect, not clinical readiness. Choice D is unrelated to immune system recovery.
