Question 1

A nurse is cleaning the wound of a 33-year-old client. The nurse cleans the wound from the center of the incision and then outward, followed by lateral motions. Which of the following best identifies this type of wound cleansing?

Accepted Answer

Horizontal

Answer

Cleaning a wound from the center of the incision outward, followed by lateral motions, describes a horizontal cleansing technique. This method is used to move contaminants away from the clean wound site, minimizing the risk of introducing bacteria into the wound. It ensures that the cleanest area (the incision) is cleaned first, and then subsequent strokes move outwards to less clean areas.

Question 2

Which of the following is NOT true of delegation?

Accepted Answer

A nurse should always delegate patient assessments.

Answer

Patient assessment is a core responsibility of a registered nurse (RN) that requires critical thinking, clinical judgment, and the application of the nursing process. These complex activities cannot be delegated to unlicensed assistive personnel (UAP) or other healthcare providers with a different scope of practice. While some data collection may be delegated, the comprehensive assessment and interpretation of findings remain the nurse's professional responsibility to ensure patient safety and appropriate care planning.

Question 3

Which of the following best represents the steps of the chain of infection?

Accepted Answer

Etiologic agent, reservoir, portal of exit, method of transmission, portal of entry to the susceptible host, susceptible host

Answer

The chain of infection outlines the six essential links required for an infectious disease to spread. These links are the etiologic agent (the pathogen), the reservoir (where it lives), the portal of exit (how it leaves the reservoir), the method of transmission (how it travels), the portal of entry (how it enters a new host), and the susceptible host (the individual who can get infected). Breaking any one of these links is crucial for preventing the spread of infection.

Question 4

There are several areas of regulation of nursing practice. Which of the following is NOT an accurate statement regarding the various methods and guidelines that regulate nursing practice?

Accepted Answer

Institutional policies are laws that are recognized by the courts and they detail how nurses are to perform their duties.

Answer

Institutional policies are facility-specific guidelines and rules that dictate how healthcare professionals are to perform their duties within that organization. They are not laws enacted by state legislatures or recognized by courts as legal statutes. Laws, such as the Nurse Practice Act, are legally binding and define the scope of nursing practice, while institutional policies provide operational guidance within that legal framework.

Question 5

The nurse applies an external electronic fetal monitor (EFM) to assess a client's uterine contractions and evaluate the fetal heart rate (FHR). However, the client is uncomfortable and changes positions frequently, making FHR hard to assess. Consequently, the physician decides to switch to an internal EFM. Before internal monitoring can begin, which of the following must occur?

Accepted Answer

The membranes must rupture

Answer

Internal electronic fetal monitoring (EFM) involves placing electrodes directly on the fetal scalp and a pressure catheter inside the uterus. For these devices to be inserted, the amniotic membranes must have ruptured. This allows direct access to the fetus and the intrauterine cavity, which is a critical prerequisite for internal monitoring.
