The nurse knows that developing appropriate nursing interventions for a patient relies on the appropriateness of the _______ diagnosis.

Correct Answer: A

Rationale: The correct answer is A: Nursing. Developing appropriate nursing interventions requires accurate nursing diagnosis, which identifies the patient's health needs and guides the care plan. Nursing interventions are specific actions taken by nurses to achieve desired patient outcomes. Medical diagnosis (B) focuses on identifying diseases or conditions, not on nursing care. Admission (C) and collaborative (D) are not directly related to developing nursing interventions. In summary, nursing interventions are tailored based on the nursing diagnosis to address the patient's unique needs.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Epistaxis refers to nosebleeds, commonly due to nasal trauma or dry air. 2. Hematemesis refers to vomiting blood, which can indicate gastrointestinal bleeding. 3. Considering hematemesis as a cause of epistaxis is important to rule out more serious conditions like gastrointestinal ulcers or cancer. 4. Intracranial hemorrhage (choice A) is less likely as it presents with neurological symptoms. 5. Intestinal hemorrhage (choice C) is less likely to cause epistaxis. 6. Hematoma of the nasal septum (choice D) may cause epistaxis but is less common than gastrointestinal bleeding. Summary: Hematemesis is the correct answer as it is a more common and relevant cause of epistaxis compared to the other choices, which are less likely and not directly related to nasal bleeding.

Correct Answer: B

Rationale: The correct answer is B: Urge incontinence. This is because Mrs. LaFarge is described as having urgency (not being able to get to the bathroom quickly) which is characteristic of urge incontinence. Stress incontinence (choice A) is associated with leakage of urine during activities that increase intra-abdominal pressure. Overflow incontinence (choice C) is characterized by incomplete bladder emptying leading to constant dribbling of urine. Functional incontinence (choice D) is due to physical or cognitive impairments that prevent a person from reaching the toilet in time. In this case, the inability to get to the bathroom quickly is more indicative of urge incontinence.

Correct Answer: C

Rationale: The correct answer is C: Density. Percussion helps assess the density of underlying tissues by producing different sounds based on the density of the tissue being tapped. Turgor (A) is assessed by skin elasticity, texture (B) refers to the feel of the skin surface, and consistency (D) is the uniformity of a substance. Density is the most relevant choice for assessing underlying tissue characteristics through percussion.

Correct Answer: D

Rationale: The correct answer is D: Rotating the lens selector dial to the red numbers to compensate for myopia. This is the correct technique because red numbers on the lens selector dial indicate the adjustment for nearsightedness (myopia) by adding concave lenses. This adjustment helps in achieving a clear view of the retina in myopic patients. A: Using the large full circle of light when assessing pupils that are not dilated is incorrect because a smaller circle of light is preferred for assessing undilated pupils to reduce glare. B: Rotating the lens selector dial to the black numbers to compensate for astigmatism is incorrect because astigmatism is corrected by adjusting the cylindrical power, not by using black numbers on the lens selector dial. C: Using the grid on the lens aperture dial to visualize the external structures of the eye is incorrect as the grid is typically used for focusing and not for visualizing external structures.
