Adult Health Nursing Study Guide Answers

Correct Answer: A

Rationale: If visible residue is noticed on the surgical instruments, it is crucial to re-sterilize them before using them for any procedure. Visible residue may indicate that the instruments are not sterile and could potentially introduce contaminants into the patient during the procedure, leading to infection or other complications. It is essential to maintain the highest standards of cleanliness and sterility in healthcare settings to ensure patient safety. Therefore, the nurse should take immediate action to re-sterilize the instruments before proceeding with any surgical procedure.

Correct Answer: C

Rationale: The presentation described is consistent with fungal keratitis. Fungal keratitis typically presents with a yellowish-white spot on the cornea, surrounded by a ring of inflammation. The filamentous opacities seen on slit-lamp examination are characteristic of fungal hyphae extending from the corneal lesion. This condition is often associated with risk factors such as trauma with vegetable matter, contact lens wear, or topical corticosteroid use. Prompt diagnosis and treatment with antifungal medications are essential to prevent complications and preserve vision.

Correct Answer: A

Rationale: Signs such as using tissues to doorknobs suggest that the patient is unconsciously controlling unacceptable impulses or feelings. This behavior falls under the category of defense mechanisms, specifically displacement, where the individual redirects their emotions from a threatening target to a safer one. In this case, the patient may be experiencing anxiety or fear related to contamination or germs, leading them to use tissues to avoid touching doorknobs directly. It is a way for the patient to manage their underlying emotions, albeit unconsciously, through this compulsive behavior.

Correct Answer: A

Rationale: Bleeding is the most serious complication of Dengue infection, typically occurring between the 4th to 7th day after the onset of symptoms. This is known as the critical phase of Dengue fever, where the patient is at a higher risk of developing severe symptoms such as bleeding manifestations. Monitoring for symptoms of bleeding during this period is crucial for timely intervention and proper management to prevent further complications or fatalities. While bleeding can occur outside this timeframe in some cases, the 4th to 7th day window is when the risk is highest and vigilance is most needed.

Correct Answer: A

Rationale: Option A indicates an understanding of the normal psychosocial development of preschoolers. It reflects the fact that during this stage, children may demonstrate frustration and have temper tantrums as they strive for independence and attempt to do things by themselves. This behavior is a common part of their development as they learn self-control, autonomy, and decision-making skills. The other options do not directly relate to normal preschooler development but rather touch upon separate issues such as separation anxiety, possessiveness, and social behaviors that are not necessarily abnormal for preschoolers.
