Anaphylactic shock is a subgroup of which type of shock?

Hypovolemic

Obstructive

Cardiogenic

Distributive

Answer and Explanation

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 B

Explanation

Choice A rationale:

Malnutrition is a risk factor for HAIs, but it is not a common cause. Malnutrition weakens the immune system, making it less able to fight off infection. However, malnutrition is not directly responsible for the introduction of pathogens into the body, which is a necessary step for the development of an HAI.

Choice C rationale:

Multiple caregivers can contribute to the spread of pathogens, but it is not a common cause of HAIs. When multiple caregivers are involved in a patient's care, there is a greater chance that one of them may be carrying a pathogen and transmit it to the patient. However, this is not the most common way that HAIs are spread.

Choice D rationale:

Chlorhexidine washes are actually used to prevent HAIs, not cause them. Chlorhexidine is an antiseptic that kills bacteria and other pathogens. It is often used to clean the skin before surgery or other invasive procedures.

Choice B rationale:

Urinary catheterization is a common cause of HAIs. A urinary catheter is a tube that is inserted into the bladder to drain urine. Catheters can introduce bacteria into the bladder, which can lead to urinary tract infections (UTIs). UTIs are the most common type of HAI.

Here are some of the reasons why urinary catheterization is a common cause of HAIs:

Catheters can introduce bacteria into the bladder. The catheter itself can act as a conduit for bacteria to enter the bladder. Bacteria can also enter the bladder around the catheter, where the catheter enters the urethra.

Catheters can irritate the bladder. This can make the bladder more susceptible to infection. Catheters can obstruct the flow of urine. This can allow bacteria to grow in the bladder.

Catheters can be difficult to keep clean. This can increase the risk of bacteria growing on the catheter and being introduced into the bladder.

A. Notify the facility’s security department B. Call the patient’s family C. Insist that the patient exit the hospital via a wheelchair D. Make sure the patient understands that they are leaving against medical advice

Correct Answer is D

Explanation

Choice A rationale:

Notifying the facility's security department may be necessary in some cases, but it should not be the nurse's first action. This could escalate the situation and make the patient feel threatened or coerced. It's important to first attempt to de-escalate the situation and understand the patient's reasons for wanting to leave. Involving security prematurely could damage the nurse- patient relationship and make it more difficult to provide care in the future.

Security should be involved if the patient is a danger to themselves or others, or if they are attempting to leave in a way that could cause harm. However, in most cases, it is best to try to resolve the situation through communication and understanding.

Choice B rationale:

Calling the patient's family may be helpful in some cases, but it is not always necessary or appropriate. The nurse should first assess the patient's decision-making capacity and their understanding of the risks of leaving against medical advice. If the patient is capable of making their own decisions, the nurse should respect their autonomy and not involve family members without their consent.

Involving family members without the patient's consent could breach confidentiality and erode trust. It's important to balance the patient's right to privacy with the potential benefits of involving family members.

Choice C rationale:

Insisting that the patient exit the hospital via a wheelchair is not necessary in most cases. If the patient is able to walk and does not pose a safety risk, they should be allowed to leave on their own terms. Requiring a wheelchair could be seen as patronizing or controlling, and it could further upset the patient.

The use of a wheelchair should be based on the patient's individual needs and preferences, not on a blanket policy.

Choice D rationale:

Making sure the patient understands that they are leaving against medical advice is the most important action the nurse can take. This ensures that the patient is aware of the potential risks of leaving the hospital, and it protects the nurse from liability. The nurse should document the patient's decision in the medical record and have the patient sign an Against Medical Advice (AMA) form.

By ensuring informed consent, the nurse respects the patient's autonomy while also fulfilling their professional obligations.
