A nurse is assisting in the care of a client who is receiving a dopamine infusion at a low dose for treatment of shock. Which of the following findings is an expected effect of this medication?

Lowered heart rate

Decreased conduction through the AV node

Increased urine output

Vasoconstriction of renal blood vessels

Answer and Explanation

The Correct Answer is C

A) Lowered heart rate:
Dopamine typically increases heart rate as it acts on beta-adrenergic receptors in the heart, leading to increased cardiac contractility and chronotropy. However, at low doses, the effect on heart rate may be minimal compared to higher doses.

B) Decreased conduction through the AV node:
Dopamine may have minimal effects on conduction through the atrioventricular (AV) node, especially at low doses. It primarily acts on adrenergic receptors to increase cardiac contractility and heart rate.

C) Increased urine output.
Dopamine is a medication commonly used to treat shock by improving cardiac output and blood pressure. At low doses, dopamine primarily acts on dopamine receptors in the renal blood vessels, causing vasodilation and increased renal blood flow. This increased renal blood flow leads to increased glomerular filtration rate (GFR) and urine output. Therefore, increased urine output is an expected effect of dopamine infusion at low doses in the treatment of shock.

D) Vasoconstriction of renal blood vessels:
At low doses, dopamine primarily acts on dopamine receptors in the renal blood vessels, causing vasodilation and increased renal blood flow. Vasoconstriction of renal blood vessels is more commonly associated with higher doses of dopamine or with other vasopressor medications such as norepinephrine or phenylephrine.

Correct Answer is ["B","C","D","E"]

Explanation

A. Wheezing: Wheezing is not a typical symptom of allergic rhinitis. It is more commonly associated with asthma or other lower respiratory conditions.

B. Sneezing: Sneezing is a common symptom of allergic rhinitis. It is often triggered by exposure to allergens such as pollen, dust mites, or pet dander.

C. Watery eyes: Watery eyes, also known as allergic conjunctivitis, frequently accompany allergic rhinitis. This symptom occurs due to inflammation of the conjunctiva in response to allergen exposure.

D. Nasal congestion: Nasal congestion, or a stuffy nose, is a hallmark symptom of allergic rhinitis. It occurs as a result of inflammation and swelling of the nasal mucosa in response to allergens.

E. Urticaria: Urticaria, commonly referred to as hives, may occur in some individuals with allergic rhinitis. However, it is more commonly associated with other types of allergic reactions, such as food allergies or drug allergies.

A. Cardiogenic shock B. Neurogenic shock C. Hypovolemic shock D. Septic shock

Correct Answer is D

Explanation

A) Cardiogenic shock:
Cardiogenic shock occurs when the heart is unable to pump enough blood to meet the body's needs, often due to myocardial infarction (heart attack) or other conditions affecting the heart's function. The client's history of a recent infection does not align with the etiology of cardiogenic shock.

B) Neurogenic shock:
Neurogenic shock occurs due to dysfunction of the autonomic nervous system, typically as a result of spinal cord injury or severe brain injury. It is characterized by widespread vasodilation and bradycardia. The client's history of a recent infection does not align with the etiology of neurogenic shock.

C) Hypovolemic shock:
Hypovolemic shock occurs due to a significant loss of blood volume, such as from trauma, hemorrhage, or dehydration. While infection can lead to fluid loss and dehydration in some cases, the client's history of a recent infection suggests a different etiology, specifically septic shock, which is driven by the systemic inflammatory response to infection.

D) Septic shock.
Septic shock is a type of distributive shock caused by a systemic response to infection. It occurs when an infection triggers a widespread inflammatory response, leading to vasodilation, increased capillary permeability, fluid loss from the bloodstream, and impaired tissue perfusion. The client's history of a recent infection suggests that the shock may be septic in nature.
