Anaphylactic shock is a subgroup of which type of shock?
Hypovolemic
Obstructive
Cardiogenic
Distributive
The Correct Answer is D
Choice A rationale:
Hypovolemic shock is a type of shock that occurs when there is a significant loss of blood or fluid volume, leading to decreased cardiac output and tissue perfusion. This can be caused by severe bleeding, dehydration, burns, or other conditions that result in fluid loss. While anaphylaxis can involve some fluid shifts, it is not primarily characterized by a loss of blood or fluid volume.
Key features of hypovolemic shock that distinguish it from anaphylactic shock include:
Prominent signs of dehydration: Dry skin and mucous membranes, decreased urine output, sunken eyes, and poor skin turgor.
Hemodynamic changes: Tachycardia, narrow pulse pressure, and cold extremities due to vasoconstriction to maintain blood pressure.
Laboratory findings: Elevated hematocrit and blood urea nitrogen (BUN) levels, indicating hemoconcentration and decreased kidney perfusion.
Choice B rationale:
Obstructive shock is a type of shock that occurs when there is an obstruction to blood flow, preventing adequate circulation to the body's tissues. This can be caused by conditions such as pulmonary embolism, cardiac tamponade, or tension pneumothorax. Anaphylaxis does not involve a physical obstruction to blood flow.
Key features of obstructive shock that distinguish it from anaphylactic shock include:
Evidence of the underlying obstruction: Jugular venous distension (cardiac tamponade), muffled heart sounds (cardiac tamponade), or respiratory distress (pulmonary embolism or tension pneumothorax).
Distinctive hemodynamic changes: Equalization of diastolic pressures between the right and left ventricles (cardiac tamponade).
Specific imaging findings: Enlarged cardiac silhouette on chest X-ray (pericardial effusion), filling defects in the pulmonary arteries on CT angiography (pulmonary embolism), or hyperexpanded lung fields with a deviated trachea on chest X-ray (tension pneumothorax).
Choice C rationale:
Cardiogenic shock is a type of shock that occurs when the heart is unable to pump enough blood to meet the body's needs. This can be caused by conditions such as heart attack, heart failure, or cardiomyopathy. Anaphylaxis does not primarily involve a failure of the heart's pumping function.
Key features of cardiogenic shock that distinguish it from anaphylactic shock include:
Evidence of heart failure: Pulmonary edema, elevated jugular venous pressure, and a third heart sound (S3 gallop).
Electrocardiogram (ECG) changes: ST-segment elevation or depression, Q waves, or other signs of myocardial ischemia or infarction.
Elevated cardiac enzymes: Troponin and creatine kinase-MB (CK-MB) levels, indicating heart muscle damage.

Correct Answer is D
Explanation
Choice A rationale:
It is not necessary to remind a patient to avoid turning from side to side after femoral artery catheterization. Restricting movement in this way could actually increase the risk of complications such as deep vein thrombosis (DVT).
Early ambulation is generally encouraged to promote circulation and prevent blood clots.
Patients are typically allowed to turn and reposition themselves as needed for comfort, unless there are specific contraindications.
Choice B rationale:
Keeping the patient in a high-Fowler's position for 6 hours is not a standard recommendation following femoral artery catheterization.
The patient's position should be based on their individual needs and comfort level.
In some cases, a slight elevation of the head of the bed may be helpful to promote venous return, but prolonged high-Fowler's positioning is not necessary.
Choice C rationale:
Passive range-of-motion exercises are not typically performed on the affected extremity immediately following femoral artery catheterization.
This is because there is a risk of dislodging the catheter or causing bleeding at the puncture site.
Once the catheter has been removed and the puncture site has healed, gentle range-of-motion exercises may be recommended to help maintain joint mobility.
Choice D rationale:
Checking pedal pulses every 15 minutes is essential to assess for adequate circulation to the lower extremities following femoral artery catheterization.
This is because there is a risk of complications such as thrombosis or embolism, which can compromise blood flow to the legs and feet.
If the pedal pulses are weak or absent, it could indicate a serious problem that requires immediate intervention.
Correct Answer is A
Explanation
Choice A rationale:
Confidentiality: Patient information stored within the facility's computer system is highly confidential and protected by various laws and regulations, such as HIPAA (Health Insurance Portability and Accountability Act). Sharing a password with anyone, even trusted colleagues, could potentially compromise patient privacy and lead to unauthorized access or breaches of sensitive data. Nurses are ethically and legally obligated to safeguard patient confidentiality and uphold the highest standards of privacy protection.
Accountability: Each nurse is held individually accountable for any actions taken under their unique login credentials. Sharing a password blurs the lines of responsibility and makes it difficult to trace actions back to the specific individual who performed them. This can create accountability issues and impede investigations in cases of errors, misconduct, or security breaches.
Security Best Practices: Password sharing is universally discouraged by cybersecurity experts as it significantly weakens system security. Strong passwords, kept confidential and changed regularly, are essential for protecting sensitive information from unauthorized access, malware, and potential cyberattacks.
Facility Policies: Most healthcare facilities have strict policies prohibiting password sharing to maintain compliance with regulations and safeguard patient privacy. Violating these policies could lead to disciplinary action, including termination of employment.
Choice B rationale:
While a nurse manager may have a legitimate need to access patient information in certain situations, sharing a password is not the appropriate method for granting such access. Facilities typically have designated procedures for authorized individuals to obtain temporary or secondary login credentials, ensuring accountability and adherence to security protocols.
Choice C rationale:
Unit clerks, while often responsible for administrative tasks within a unit, do not have a clinical role that necessitates access to patient information through the nurse's password. Sharing a password with a unit clerk could lead to unauthorized access and potential privacy violations.
Choice D rationale:
The facility's information system representative is responsible for maintaining the technical infrastructure of the computer system, but they do not require access to patient information through individual nurse passwords. They have their own authorized means of accessing the system for troubleshooting and maintenance purposes.
