A nurse is reinforcing teaching about foot care with a client who has type 2 diabetes mellitus. Which of the following statements by the client Indicates an understanding of the teaching?

Tuberculosis is a highly contagious airborne infection caused by Mycobacterium tuberculosis, transmitted through airborne droplet nuclei that remain suspended in the air for prolonged periods. Infection control requires airborne precautions to prevent inhalation of infectious particles by healthcare workers and other clients. Proper personal protective equipment (PPE), specialized room placement, and respiratory protection are essential components of care. Nurses must understand the difference between airborne, droplet, and contact precautions to ensure safety.

Rationale:
A. An N95 respirator is required because it provides a tight seal and filters airborne particles effectively, protecting the nurse from inhaling infectious droplet nuclei. In the care of clients with conditions such as Tuberculosis, airborne precautions mandate use of N95 or higher-level respiratory protection. This is the correct and essential PPE during routine care.

B. Shoe protectors are not routinely required for tuberculosis care because transmission does not occur through footwear contamination. TB is spread via airborne particles, not contact with contaminated floors or fluids. Therefore, shoe covers do not provide meaningful protection in this context.

C. Sterile gloves are not necessary for routine care of a tuberculosis client unless performing a sterile procedure. Standard clean gloves are sufficient for most interactions. TB precautions focus primarily on respiratory protection rather than sterile technique.

D. A surgical mask is not adequate protection for the nurse because it does not effectively filter airborne particles. Surgical masks are used for droplet precautions, not airborne infections like tuberculosis. The client, however, may wear a surgical mask during transport to reduce spread.

This question focuses on prioritization of care in a client presenting with signs and symptoms highly suggestive of an ectopic pregnancy. The client has a positive pregnancy test, delayed menses, right lower quadrant abdominal tenderness, and vaginal spotting, along with a history of pelvic inflammatory disease, which increases risk for ectopic implantation. A rising heart rate alongside abdominal pain and bleeding raises concern for possible internal hemorrhage and early hypovolemia. In obstetric emergencies, priority is given to identifying hemodynamic instability first, followed by addressing ongoing sources of bleeding.

Rationale for correct choices:

• Heart rate: An increasing heart rate from 90/min to 104/min is an early compensatory response to possible internal blood loss, which is highly concerning in suspected ectopic pregnancy. Tachycardia may indicate the beginning of hypovolemia even before significant changes appear in blood pressure or hemoglobin. In this context, the priority is to assess for potential rupture and hemorrhage. Monitoring and addressing circulatory instability is essential to prevent rapid deterioration.

• Vaginal spotting: Vaginal spotting in early pregnancy, especially in combination with abdominal pain and a positive hCG, is a key indicator of possible ectopic pregnancy or threatened pregnancy loss. The presence of dark red spotting suggests older blood and possible ongoing bleeding. This finding requires immediate evaluation because it may reflect bleeding from an abnormal implantation site. Managing and monitoring bleeding is critical after stabilizing circulation.

Rationale for incorrect choices:

• Bowel sounds: Hyperactive bowel sounds are not a priority concern in this scenario and may be related to anxiety, hormonal changes, or nonspecific gastrointestinal activity. They do not directly indicate hemodynamic instability or pregnancy complications. While abdominal assessment is important, bowel sounds are not the most urgent finding compared to signs of bleeding or circulatory compromise. Therefore, they are not prioritized in this situation.

• Lung sounds: The client’s lung sounds are only described as slight inspiratory wheezes, likely related to the history of asthma. There are no signs of respiratory distress, hypoxia, or acute pulmonary compromise. Respiratory status is stable compared to the potential for hemorrhagic shock in suspected ectopic pregnancy. Thus, lung findings are not the immediate priority.

• Anxiety: Anxiety is an expected emotional response given the uncertainty of pregnancy complications and does not pose an immediate physiological threat. While important for supportive care, it does not take priority over signs of possible internal bleeding or hemodynamic instability. Addressing anxiety is part of holistic care but is secondary to stabilizing circulation and monitoring bleeding.

• Hemoglobin level: Although hemoglobin is slightly low, it has not yet shown a critical drop and may not reflect acute blood loss at this stage. Hemoglobin changes often lag behind actual bleeding, especially in early hemorrhage. Therefore, relying on hemoglobin alone could delay recognition of worsening instability. Continuous monitoring is important, but heart rate and active bleeding provide more immediate clinical cues.
