ATI NUR 130 Final Exam

Correct Answer: Immobility

Detailed Explanation of the Correct Answer:

Immobility is the primary factor contributing to the development of pressure injuries in patients with impaired sensory perception. When patients cannot feel discomfort or pain, they may not recognize the need to change position. As a result, they remain in one position for too long, leading to sustained pressure on certain areas of the body, particularly over bony prominences. This prolonged pressure reduces capillary blood flow, causing ischemia, tissue damage, and eventually pressure injuries.

Patients with conditions such as spinal cord injuries, advanced diabetes with neuropathy, or stroke often have decreased sensation and rely on caregivers or regular repositioning to prevent skin breakdown.

Explanation of Incorrect Options:

Increased Moisture – While moisture can weaken skin integrity and contribute to maceration, it is not the primary factor in pressure injury development related to impaired sensory perception. It is more directly associated with incontinence-related skin issues.

Friction and Shear – Friction and shear are mechanical forces that can exacerbate skin breakdown, especially during repositioning or movement. However, they are secondary factors and not specifically tied to sensory perception loss.

Decreased Tissue Perfusion – This is an important contributing factor in pressure injury development overall, but in the context of impaired sensory perception, immobility is more directly linked, as the patient cannot feel the need to move or shift pressure points.

Summary:

Patients with impaired sensory perception are at greatest risk of developing pressure injuries due to immobility, which leads to unrelieved pressure on the skin. While other factors like moisture, friction, and perfusion affect skin integrity, immobility is the primary concern in this specific context.

Correct Answer: Tissue integrity

Explanation of Correct Answer:

Tissue integrity

This term refers to the state in which the epithelial tissues (such as skin and mucous membranes) are structurally intact and physiologically functioning. Tissue integrity is crucial for protecting the body from pathogens, maintaining fluid balance, and supporting temperature regulation. When tissue integrity is compromised—due to injury, disease, or pressure—it can lead to infections, delayed healing, or other complications.

Explanation of Incorrect Answers:

Homeostasis

Incorrect. Homeostasis is the process by which the body maintains internal stability (such as temperature, pH, and electrolyte balance). It does not specifically refer to the structure or function of epithelial tissues.

Tissue cohesion

Incorrect. Tissue cohesion refers to the ability of cells within tissues to stick together, which is a component of tissue integrity but not the comprehensive concept. It lacks the full scope of physiological function and structure described in the question.

Cellular regulation

Incorrect. Cellular regulation refers to the processes that control cell function, such as growth, division, and repair. It plays a role in maintaining tissue integrity but does not directly refer to the intact state of epithelial tissues.

Summary:

The term that specifically refers to the intact and functioning state of epithelial tissues like skin and mucous membranes is tissue integrity. While homeostasis, tissue cohesion, and cellular regulation are related physiological processes, they do not fully capture the concept described in the question.

Correct Answers:

Determine whether outcomes or standards are met

Document results of goal achievement

Use self-reflection and correct errors

Detailed Explanation of Each Correct Answer:

Determine whether outcomes or standards are met

This is a core activity in the evaluation phase. The nurse must assess whether the patient has achieved the expected outcomes or goals that were set during the planning phase.

Document results of goal achievement

Accurate documentation is essential in the evaluation phase. The nurse must record whether the patient met, partially met, or did not meet the care goals.

Use self-reflection and correct errors

Evaluation includes critical thinking and reflection. Nurses reflect on what worked and what didn’t, which helps guide future care and correct any mistakes or gaps in the care plan.

Why the Incorrect Options Are Wrong:

Set priorities for patient care

This is part of the planning phase, not evaluation. Setting priorities involves choosing which problems to address first, based on urgency and patient needs.

Ambulate patient 25 feet in the hallway

This is part of the implementation phase, where nursing interventions are carried out. Evaluation would involve assessing how the patient responded to this activity—not doing it.

Summary:

The evaluation phase of the nursing process focuses on assessing outcomes, documenting progress, and reflecting on care effectiveness. The correct actions for this phase are b, d, and e.

Correct Answer: No bubbling is present in the suction control chamber of the drainage device.

Detailed Explanation of the Correct Answer:

No bubbling is present in the suction control chamber of the drainage device

This is a critical issue when a patient is placed on low constant suction using a wet suction system. In a traditional water-based suction system, you should see continuous gentle bubbling in the suction control chamber when suction is functioning properly. No bubbling indicates that:

Suction may not be working (disconnected tubing, blocked suction, malfunctioning equipment)

There is no negative pressure, meaning the system is not effectively removing air or fluid from the pleural space

This compromises the purpose of the chest tube and can lead to reaccumulation of air or fluid, resulting in worsening pneumothorax or pleural effusion, and requires immediate nursing action.

Explanation of Incorrect Options:

The patient reports pain at the chest tube insertion site that increases with movement

This is a common and expected symptom post chest tube insertion. It should be monitored and managed with analgesics, but it’s not an emergency unless the pain is sudden and severe or associated with signs of complications.

Fifty milliliters of blood gushes into the drainage device after the patient coughs

While this might appear alarming, coughing can dislodge clots or mobilize secretions, leading to sudden drainage. As long as it doesn't continue or turn into massive hemorrhage, it’s usually a transient event and can be observed.

Yellow purulent discharge is seen leaking out from around the dressing site

This is very concerning and requires action, but not as immediate as the failure of the suction system. An infection develops over time, whereas loss of suction can lead to rapid decompensation from unresolved pneumothorax.

Summary:

While purulent drainage (Option D) is serious, the immediate threat to respiratory function from loss of suction pressure (Option C) is more urgent. No bubbling in the suction chamber suggests suction failure, which means the chest tube is not working properly, making C the correct answer.

Correct Answer: a 24-year-old with acute respiratory distress syndrome requiring mechanical ventilation

Detailed Explanation of the Correct Answer:

24-year-old with acute respiratory distress syndrome (ARDS) requiring mechanical ventilation

Closed suction systems are most appropriate for patients who are intubated and receiving mechanical ventilation, particularly in critical care situations like ARDS. A closed suction system allows the nurse to suction secretions without disconnecting the patient from the ventilator, which helps maintain oxygenation and PEEP (positive end-expiratory pressure)—crucial in ARDS. It also reduces the risk of infection by keeping the circuit closed.

Why the Incorrect Options Are Wrong:

5-year-old with excessive drooling from epiglottitis

This is an emergency airway condition and suctioning is contraindicated. Any attempt to suction or disturb the airway could cause complete airway obstruction due to inflammation of the epiglottis. This patient requires immediate airway management in a controlled setting like an OR or ICU.

5-year-old with an asthma attack following severe allergies

This patient may need bronchodilators and oxygen, but routine suctioning is not typically required unless secretions are excessive and causing obstruction. Asthma is usually managed pharmacologically, not with mechanical ventilation and closed suctioning.

24-year-old with a right pneumothorax following a motor vehicle accident

Although this is a serious condition, a pneumothorax is treated primarily with a chest tube, not with suctioning of the airway. Closed suction would not be relevant unless this patient is intubated and ventilated, which is not stated.

Summary:

Closed suction devices are best used for patients on mechanical ventilation, where maintaining a closed system helps support oxygenation and reduces infection risk. In this scenario, the patient with ARDS requiring ventilation is the most appropriate candidate for closed suctioning.

Correct Answer: Complicated grief

Detailed Explanation of the Correct Answer:

Complicated grief

Complicated grief is a prolonged, intense, and disabling form of grief that interferes with normal functioning. It often persists well beyond the expected time frame for grieving (in this case, 2 years after the loss). The nurse is showing clear signs of emotional and functional impairment, including breakdowns at work and at home, which is consistent with complicated grief. People experiencing this form of grief may feel stuck, unable to move forward or cope with daily life.

Why the Incorrect Options Are Wrong:

Normal grief

Normal grief typically includes a range of emotional responses that gradually diminish over time and allow the person to return to functional living. Since the nurse is still emotionally overwhelmed and her functioning has declined 2 years after the loss, this exceeds the typical pattern and time frame of normal grief.

 Perceived grief

Perceived grief refers to a loss that is not outwardly recognized by others (such as loss of independence or job). The loss in this scenario (a spouse) is a recognized and tangible loss, making this term inapplicable.

Disenfranchised grief

Disenfranchised grief is experienced when a loss cannot be openly acknowledged or publicly mourned, such as the death of a secret partner or a miscarriage not shared with others. The nurse’s grief over her spouse, a socially recognized loss, does not meet the definition of disenfranchised grief.

Summary:

The female nurse is struggling with intense and prolonged emotional pain, well past the usual grief period, and it is interfering with her daily life and work. This pattern reflects complicated grief, not normal, perceived, or disenfranchised grief.

Correct Answers:

Observations of wound healing

Daily blood pressure measurements

Findings of respiratory rate and depth

 Patient's subjective report of feelings about a new diagnosis of cancer

Detailed Explanation of Each Correct Answer:

Observations of wound healing

This is an objective evaluative measure. The nurse visually examines the wound to assess whether the care plan is effective in promoting healing.

Daily blood pressure measurements

This is a quantitative, objective measure used to evaluate whether interventions (e.g., medication, lifestyle changes) are helping control blood pressure.

Findings of respiratory rate and depth

This is another objective assessment that helps determine the effectiveness of respiratory interventions such as breathing treatments or oxygen therapy.

Patient's subjective report of feelings about a new diagnosis of cancer

Subjective data—what the patient says or feels—is an important evaluative measure when assessing emotional and psychological responses to care, especially for new diagnoses.

Why the Incorrect Option Is Wrong:

Completion of nursing interventions

This reflects nursing action, not patient response. While it’s important to document what was done, evaluation focuses on how the patient responded to the care provided—not whether tasks were completed.

Summary:

Evaluative measures focus on the patient's response to care, both objective (e.g., wound healing, vital signs) and subjective (e.g., emotional responses). The correct evaluative measures are a, b, c, and e.

Correct Answer: Infection

Explanation of Correct Answer:

Infection

Mucous membranes secrete mucus as a protective barrier that traps pathogens like bacteria, viruses, and dust particles. These membranes line body cavities that are open to the outside environment—such as the respiratory, gastrointestinal, and genitourinary tracts. The mucus helps to:

Trap microorganisms and foreign particles

Prevent the entry and colonization of pathogens

Support immune defense through the presence of antibodies (like IgA) and enzymes

This secretion is a critical part of the body's innate immune system, especially in areas constantly exposed to potential infection sources.

Explanation of Incorrect Answers:

Dehydration

Incorrect. While mucus has moisturizing properties, its primary function is not to prevent dehydration. The skin and systemic fluid balance mechanisms primarily regulate dehydration.

Hypothermia

Incorrect. Mucus does not play a significant role in temperature regulation. Hypothermia is prevented mainly by metabolic processes, muscle activity (shivering), and insulation from the skin and subcutaneous tissue.

Allergic reactions

Incorrect. Mucous membranes can be affected by allergic reactions (e.g., nasal congestion during hay fever), but secreting mucus does not prevent allergies. In fact, excessive mucus is often a response to allergens.

Summary:

Mucous membranes protect against infection by secreting mucus, which traps pathogens and facilitates their removal from the body. This is a crucial first-line defense of the immune system.

Correct Answer: Oxygen saturation 88%

Detailed Explanation of the Correct Answer:

Oxygen saturation 88%

Suctioning can cause hypoxia if not done carefully. If the patient’s oxygen saturation drops below 90%, it indicates significant hypoxemia, and suctioning should be stopped immediately. An SpO₂ of 88% is below the acceptable threshold and can compromise oxygen delivery to tissues. The nurse should discontinue suctioning, administer oxygen if needed, and allow the patient to recover before attempting again.

Why the Incorrect Options Are Wrong:

Pulse 75

This pulse rate is within the normal adult range (60–100 bpm) and represents a slight increase from baseline. It does not indicate a problem requiring cessation of suctioning.

Pulse 80

Also within normal range, this pulse rate is a benign finding and does not signal any complication during suctioning.

Oxygen saturation 91%

Although this is a slight drop from the baseline of 94%, an SpO₂ of 91% is still considered acceptable during suctioning. It should prompt close monitoring, but does not yet warrant stopping the procedure.

Summary:

The most concerning finding during suctioning is a drop in oxygen saturation to 88%, which indicates hypoxemia and requires the nurse to stop suctioning immediately to prevent further compromise. Minor increases in pulse or slight SpO₂ drops (still >90%) do not necessitate stopping.
