The nurse is educating her patient on the pumping efficacy of the heart.
The nurse knows that the patient understands the teaching when the patient states:
There are no chambers.
Large chambers called ventricles.
Small chambers called ventricles.
Large chambers called the atrium.
The Correct Answer is B
Choice A rationale:
This statement is incorrect because the heart has four chambers: two atria and two ventricles.
Choice B rationale:
This statement is correct. The heart has two large chambers called ventricles that pump blood out of the heart.
Choice C rationale:
This statement is incorrect because the ventricles are the larger chambers of the heart, not the smaller ones.
Choice D rationale:
This statement is incorrect because the atria are the smaller chambers of the heart, not the larger ones.

Correct Answer is C
Explanation
Choice A rationale:
Frozen dinners are often high in sodium, which can increase blood pressure, so they are not a good choice for someone with hypertension.
Choice B rationale:
Processed cheese products are also high in sodium, so they should be avoided.
Choice C rationale:
Seasoning food with herbs and spices is a healthy way to add flavor without adding sodium.
Choice D rationale:
Soy sauce is very high in sodium, so it should not be used as a marinade for meats.
Correct Answer is B
Explanation
The correct answer is choice B.
Choice A rationale:
A client who has NPO (nothing by mouth) status since midnight for an endoscopy could be at risk for fluid volume deficit. NPO status means the client has not been able to consume fluids orally, which could lead to a decrease in fluid intake. However, the risk is relatively low if the NPO status has only been in place since midnight and the client is otherwise healthy.
Choice B rationale:
A client who has heart failure and is receiving diuretic therapy is at a high risk for fluid volume deficit. Diuretics are used in heart failure to remove excess fluid from the body, but they can also lead to fluid volume deficit if not properly managed. This is because diuretics increase urine output, which can lead to a loss of fluid and electrolytes.
Choice C rationale:
A client who has gastroenteritis and is receiving oral fluids is not typically at risk for fluid volume deficit. Gastroenteritis can cause fluid loss through diarrhea and vomiting, but if the client is able to consume and retain oral fluids, they can usually maintain their fluid balance.
Choice D rationale:
A client who has end-stage kidney disease and will undergo dialysis could be at risk for fluid volume deficit, but this risk is typically well-managed during dialysis. Dialysis removes waste and excess fluid from the blood, and fluid intake is carefully monitored and adjusted based on the individual’s needs. Therefore, while there is a potential risk, it is usually well-controlled under the care of healthcare professionals.
