A nurse is evaluating patients who have been prescribed intravenous therapy. Which observation for a patient with a Peripherally Inserted Central Catheter (PICC) demands immediate attention?
The PICC was inserted 4 weeks ago.
The initial site dressing is 3 days old.
A securement device is missing.
Swelling is observed in the upper extremity.
The Correct Answer is D
Choice A rationale:
While PICCs are typically intended for shorter-term use (up to 12 weeks), the fact that a PICC has been in place for 4 weeks is not, in itself, an immediate cause for concern. Regular assessment of the catheter and site is crucial, but the duration of placement alone does not warrant immediate attention.
Choice B rationale:
While it's generally recommended to change PICC dressings every 7 days, a dressing that is 3 days old is not an immediate emergency. The nurse should prioritize changing the dressing as soon as possible, but it does not require the same level of urgency as other potential complications.
Choice C rationale:
A missing securement device is a concern because it can increase the risk of catheter dislodgement or migration. However, it does not necessarily indicate an immediate threat to the patient's well-being. The nurse should promptly address the missing securement device, but it would not be the most pressing issue compared to swelling in the extremity.
Choice D rationale:
Swelling in the upper extremity where the PICC is located is a significant finding that demands immediate attention. It can be a sign of several serious complications, including:
Thrombosis: A blood clot within the vein, which can obstruct blood flow and lead to pain, swelling, and potentially more severe consequences like deep vein thrombosis (DVT) or pulmonary embolism (PE).
Infection: Inflammation and infection at the insertion site or within the bloodstream, which can cause swelling, redness, warmth, and pain. If left untreated, infection can progress to sepsis, a life-threatening condition.
Phlebitis: Inflammation of the vein, which can cause pain, redness, and swelling along the vein.
Infiltration: Leakage of fluids or medications into the surrounding tissue, leading to swelling and discomfort.
Prompt action is crucial in these cases to prevent further complications and ensure patient safety. The nurse should immediately notify the appropriate healthcare provider, initiate necessary interventions, and closely monitor the patient's condition.

Correct Answer is A
Explanation
Choice A rationale:
Addresses the family's fear directly: By demonstrating how to avoid spreading the disease, the nurse directly addresses the family's primary concern, which is the fear of contracting the infection. This proactive approach provides education and reassurance, empowering the family to make informed decisions about visitation.
Promotes understanding and adherence to precautions: Clear instruction on how to don and doff personal protective equipment, hand hygiene techniques, and other infection control measures increases the likelihood that the family will follow the precautions correctly, reducing the risk of transmission.
Empowers the family to make informed choices: By providing knowledge and skills, the nurse enables the family to feel more confident in their ability to visit safely. This sense of control can help to alleviate anxiety and promote positive coping mechanisms.
Facilitates open communication and trust: The demonstration creates an opportunity for the nurse to answer questions, address concerns, and build rapport with the family. This open dialogue can foster trust and collaboration, which are essential for effective care.
Choice B rationale:
May provide false reassurance: While it's important to offer support and hope, it's not always possible to guarantee that family members will not contract the infection. Absolute reassurances could potentially lead to complacency or disregard for precautions, increasing the risk of transmission.
Fails to address the need for education: Simply stating that the family won't get sick doesn't provide them with the knowledge and skills needed to protect themselves and the client. This lack of understanding could result in accidental transmission.
Choice C rationale:
May pressure the family: Encouraging visitation without addressing underlying fears and concerns could be perceived as pressure, leading to resentment, anxiety, or even avoidance. It's important to respect the family's decision-making process and provide support regardless of their choice.
Doesn't prioritize safety: While emotional support is important, the primary focus should be on ensuring the safety of both the client and the family. Encouraging visitation without proper education and precautions could compromise safety.
Choice D rationale:
Focuses on compliance rather than understanding: Informing the family about legal mandates may come across as authoritarian and could potentially increase anxiety or resistance. It's more effective to focus on the rationale behind the precautions and emphasize their role in protecting both the client and the family.
Misses an opportunity to build trust: Simply stating the rules without engaging in dialogue may hinder open communication and trust-building. Taking a collaborative approach and addressing concerns can lead to better understanding and adherence to precautions.
Correct Answer is D
Explanation
Choice A rationale:
Metabolic alkalosis is a condition characterized by an increase in the pH of the blood due to an excess of bicarbonate (HCO3-) in the body. It is not typically caused by severe diarrhea. In fact, diarrhea can often lead to a loss of bicarbonate, which can contribute to metabolic acidosis.
Causes of metabolic alkalosis include: excessive vomiting, use of diuretics, and excessive intake of alkali such as antacids. Clinical manifestations of metabolic alkalosis include: muscle twitching, paresthesias, seizures, confusion, and lethargy.
Choice B rationale:
Respiratory alkalosis is a condition characterized by a decrease in the partial pressure of carbon dioxide (PaCO2) in the blood, leading to an increase in blood pH. It is caused by hyperventilation, which removes excess CO2 from the body. Severe diarrhea does not typically cause hyperventilation.
Causes of respiratory alkalosis include: anxiety, hyperventilation syndrome, high altitude sickness, and pulmonary embolism. Clinical manifestations of respiratory alkalosis include: lightheadedness, dizziness, paresthesias, palpitations, and tetany.
Choice C rationale:
Respiratory acidosis is a condition characterized by an increase in the partial pressure of carbon dioxide (PaCO2) in the blood, leading to a decrease in blood pH. It is caused by hypoventilation, which prevents the body from removing enough CO2. Severe diarrhea does not typically cause hypoventilation.
Causes of respiratory acidosis include: chronic obstructive pulmonary disease (COPD), pneumonia, asthma, and neuromuscular disorders.
Clinical manifestations of respiratory acidosis include: headache, confusion, somnolence, and coma.
Choice D rationale:
Metabolic acidosis is a condition characterized by a decrease in the pH of the blood due to an excess of acid in the body or a loss of bicarbonate. Severe diarrhea can lead to metabolic acidosis through several mechanisms:
Loss of bicarbonate in the stool: Diarrhea often contains a significant amount of bicarbonate, which can be lost from the body in large amounts during severe diarrheal episodes. This loss of bicarbonate can lead to a decrease in the blood's pH, resulting in metabolic acidosis.
Dehydration: Severe diarrhea can also lead to dehydration, which can concentrate acids in the blood and contribute to metabolic acidosis.
Lactic acidosis: In some cases, severe diarrhea can also cause lactic acidosis, a type of metabolic acidosis that occurs when there is a buildup of lactic acid in the body. This can happen due to impaired circulation or tissue hypoxia, which can occur as a complication of severe diarrhea.
