Adult Health Nursing Study Guide Answers

Correct Answer: D

Rationale: Using aseptic technique and sterile equipment during catheter insertion is crucial for minimizing the risk of infection during bladder catheterization. Aseptic technique involves maintaining a sterile field, washing hands thoroughly, using sterile gloves, and ensuring that all equipment used is sterile. By following these practices, the nurse can prevent introducing bacteria into the urinary tract, reducing the likelihood of infection in the patient. While cleansing the perineal area with antiseptic solutions is important for general hygiene, the priority for infection prevention during catheterization lies in maintaining a sterile environment during the procedure. Administering prophylactic antibiotics is not routinely recommended for catheterization unless there are specific risk factors present.

Correct Answer: A

Rationale: Beta-blockers are a class of medications commonly used to manage hypertension. One of the main mechanisms of action of beta-blockers is to reduce heart rate and contractility by blocking the beta-adrenergic receptors in the heart. As a result, one of the potential adverse effects of beta-blockers is bradycardia, which refers to a slower than normal heart rate. Therefore, the nurse should closely monitor the patient for signs and symptoms of bradycardia when starting or adjusting the dose of a beta-blocker. Symptoms of bradycardia may include dizziness, fainting, fatigue, or shortness of breath. If bradycardia is severe or symptomatic, it may require dose adjustments or discontinuation of the beta-blocker to prevent complications.

Correct Answer: B

Rationale: The gallbladder is the structure responsible for storing and concentrating bile produced by the liver until it is needed for digestion. Bile is a digestive fluid that helps in the breakdown of fats during the digestive process. When food containing fats enters the small intestine, the gallbladder contracts and releases bile into the small intestine to aid in the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, storing it until it is needed for digestion.

Correct Answer: C

Rationale: It is crucial to have a complete set of surgical instruments for any surgical procedure to ensure patient safety and the success of the surgery. If the nurse notices that the surgical instrument tray is incomplete, the best course of action is to inform the sterile processing department immediately. By doing so, the missing instruments can be promptly provided, ensuring that the surgical team has all the necessary tools for the procedure. Proceeding with the procedure using incomplete instruments can compromise patient safety and the quality of care provided. Documenting the missing instruments in the surgical count log is important for record-keeping purposes but should not delay the immediate action of requesting additional instruments. Borrowing instruments from another OR is not recommended as it can create confusion, potential cross-contamination, and disrupt the workflow of another surgical team.

Correct Answer: C

Rationale: Qualitative research design focuses on gaining an in-depth understanding of attitudes, beliefs, motivations, and behaviors of individuals or groups. It does not typically involve statistical analysis or estimation of relationships between variables like quantitative designs do. Qualitative research involves collecting data through methods such as interviews, observations, or focus groups to provide rich and detailed insights into the experiences and perspectives of the participants. The emphasis is on understanding the meanings individuals attach to their experiences, rather than generalizing findings to a larger population.
