Adult Health Nursing Study Guide Answers

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: Nurses play a crucial role as collaborators in the diagnostic process of psychiatric patients. While nurses themselves do not diagnose psychiatric conditions, they work closely with other healthcare providers such as psychiatrists and psychologists in assessing and monitoring patients' mental health status. Nurses gather valuable information, observe patients' behaviors, and communicate effectively with the healthcare team to contribute to the overall diagnostic process. By actively participating in assessments and evaluations, nurses help ensure accurate diagnoses and appropriate treatment plans for psychiatric patients.

Correct Answer: D

Rationale: For a diagnostic pelvic ultrasound, one important preparation is to have the patient void or empty their bladder before the procedure. This allows for better visualization of the pelvic organs and structures during the ultrasound scan. A full bladder can obstruct the view and make it difficult to obtain accurate images. Therefore, it is essential for the patient to follow instructions to empty their bladder before the pelvic ultrasound to ensure the best results.

Correct Answer: B

Rationale: Uterine hyperstimulation, also known as tachysystole, is a condition characterized by frequent and intense uterine contractions with minimal rest intervals. This can lead to maternal fatigue and decreased fetal oxygenation due to the insufficient time for the uterus to relax and refill with oxygenated blood between contractions. Uterine hyperstimulation can be caused by various factors such as excessive use of uterotonics (oxytocin or prostaglandins), improper labor induction techniques, or maternal conditions like previous uterine surgery. It is essential for the nurse to assess for signs of uterine hyperstimulation and take appropriate interventions to prevent potential complications for both the mother and the baby.

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.
