In which type of water would a submersion injury cause the patient's fluid to be drawn from the vascular space into the alveoli, impairing alveolar ventilation and resulting in hypoxia?

Hypotonic saltwater.

Hypertonic saltwater.

Hypotonic freshwater.

Hypertonic freshwater.

Answer and Explanation

The Correct Answer is B

The correct answer is B. Hypertonic saltwater.

Choice A rationale: Hypotonic saltwater would not cause significant fluid shifts into the alveoli. Instead, it would cause cells to swell due to the lower concentration of solutes outside the cells.

Choice B rationale: Hypertonic saltwater causes fluid to be drawn from the vascular space into the alveoli due to the higher concentration of solutes in the water compared to the body's cells. This can impair alveolar ventilation and result in hypoxia.

Choice C rationale: Hypotonic freshwater would cause cells to swell and potentially burst due to the lower concentration of solutes outside the cells, but it would not specifically cause fluid to be drawn into the alveoli.

Choice D rationale: Hypertonic freshwater is not a common classification for drowning water. Freshwater is typically hypotonic compared to body fluids, and it would not cause the same fluid shift as hypertonic saltwater.

Correct Answer is ["A","B","D"]

Explanation

Choice A rationale:

Increased bilirubin levels can occur in thalassemia major due to the destruction of red blood cells, leading to elevated bilirubin, which is a breakdown product of hemoglobin. This elevation can contribute to jaundice and other symptoms.

Choice B rationale:

Thalassemia major leads to the destruction of red blood cells, causing the bone marrow to release more reticulocytes (immature red blood cells) into the bloodstream. Therefore, an increased reticulocyte level is expected in thalassemia major.

Choice C rationale:

Increased mean corpuscular volume (MCV) is not a typical finding in thalassemia major. Thalassemia major is characterized by microcytic (smaller than normal) red blood cells, leading to a decreased MCV.

Choice D rationale:

Thalassemia major causes increased iron absorption by the intestines, leading to elevated total iron-binding capacity (TIBC) TIBC measures the body's capacity to bind and transport iron in the blood, and elevated levels are seen in conditions with increased iron demand, such as thalassemia major.

A. "I will take a walk daily.” B. "I will try to lose at least 20 pounds.” C. "I will put on my stockings after I get out of bed each day.” D. "I will not wear knee-high socks that are tight around my calf.”

Correct Answer is D

Explanation

Choice A rationale:

Taking a daily walk is a beneficial activity for patients with venous leg ulcers. Walking promotes blood circulation, which can aid in wound healing. This statement indicates that the patient understands the importance of physical activity for their condition.

Choice B rationale:

Trying to lose weight is another positive step for a patient with venous leg ulcers, especially if the patient is overweight. Excess body weight can put additional pressure on the veins in the legs, worsening venous insufficiency. Losing weight can alleviate this pressure and improve venous circulation, supporting the healing process of leg ulcers.

Choice C rationale:

Wearing stockings after getting out of bed is a proper technique for managing venous leg ulcers. Compression stockings help improve blood flow in the legs and reduce swelling, which is beneficial for patients with venous insufficiency and leg ulcers. This statement indicates that the patient understands the importance of wearing compression stockings consistently.

Choice D rationale:

Not wearing knee-high socks that are tight around the calf is essential advice for patients with venous leg ulcers. Tight clothing, including socks or stockings, can impede blood circulation in the legs, worsening venous insufficiency and delaying wound healing. This statement indicates the need for further education because the patient should avoid any tight clothing around the affected area to promote optimal blood flow and wound healing.
