A nurse is caring for a client who has been taking oxymetazoline (Afrin) nasal spray for the past 10 days for allergic rhinitis. The nurse should monitor the client for which of the following manifestations as an adverse effect of this medication?
Sedation
Constipation
Productive cough
Nasal congestion
The Correct Answer is D
A) Sedation:
Sedation is not an adverse effect commonly associated with oxymetazoline nasal spray. Oxymetazoline works by constricting blood vessels in the nasal passages to relieve congestion and does not typically cause sedation.
B) Constipation:
Constipation is not an adverse effect associated with oxymetazoline nasal spray. Constipation is more commonly associated with medications that affect the gastrointestinal system, such as opioid analgesics or certain anticholinergic medications.
C) Productive cough:
Productive cough is not an adverse effect commonly associated with oxymetazoline nasal spray. Productive cough refers to a cough that produces mucus or phlegm and is more often associated with respiratory infections or chronic respiratory conditions.
D) Nasal congestion.
Oxymetazoline (Afrin) is a nasal decongestant spray commonly used for the temporary relief of nasal congestion associated with allergic rhinitis or the common cold. However, if oxymetazoline nasal spray is used for more than 3 to 5 consecutive days, it can lead to rebound congestion, also known as rhinitis medicamentosa. Rebound congestion occurs when the nasal mucosa becomes dependent on the medication for vasoconstriction, and upon discontinuation, nasal congestion worsens. Therefore, prolonged use of oxymetazoline nasal spray can result in a worsening of nasal congestion as an adverse effect.

Correct Answer is ["A","B","E"]
Explanation
A. The inside surface of the lungs is small, and the dose is concentrated in that area: Inhalation medications are delivered directly to the lungs, where they are rapidly absorbed due to the small surface area and the close proximity of the medication to the lung tissue.
B. There is a large surface area inside the lungs: The lungs have a large surface area for gas exchange, allowing for efficient absorption of inhaled medications into the bloodstream.
C. Inhaled medications are given at very high doses: Inhaled medications are typically given at therapeutic doses appropriate for the patient's condition. While they may be given in higher doses compared to oral medications in some cases, the dosage is carefully adjusted based on factors such as the patient's age, weight, and severity of the condition.
D. Inhaled medications are given with food: Inhaled medications are typically administered separately from meals. Food can interfere with the absorption of inhaled medications and may affect their effectiveness.
E. There is a rich blood supply to the lungs: The lungs have a rich network of blood vessels, known as pulmonary capillaries, which allows for rapid absorption of inhaled medications into the bloodstream.
Correct Answer is C
Explanation
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.
