A nurse is providing teaching to a client who has a family history of hypertension. The nurse should inform the client that his blood pressure of 124/79 mm Hg places him in which of the following categories?

Elevated

Stage 1 hypertension

Stage 2 hypertension

Normal

Answer and Explanation

The Correct Answer is A

Choice A reason: A blood pressure reading of 124/79 mm Hg is considered elevated. The normal range for blood pressure is less than 120/80 mm Hg. Elevated blood pressure is when readings consistently range from 120129 systolic and less than 80 mm Hg diastolic.

Choice B reason: Stage 1 hypertension is defined by a systolic blood pressure ranging from 130 to 139 mm Hg or a diastolic pressure ranging from 80 to 89 mm Hg. The client's blood pressure does not fall into this category.

Choice C reason: Stage 2 hypertension is characterized by a systolic blood pressure of 140 mm Hg or higher or a diastolic pressure of 90 mm Hg or higher. The client's blood pressure is below these levels.

Choice D reason: A normal blood pressure reading is typically below 120/80 mm Hg. Although the client's diastolic pressure is within the normal range, the systolic pressure is above normal, thus it does not qualify as a normal blood pressure reading.

Correct Answer is B

Explanation

Choice A reason: The normal range for serum creatinine is indeed 0.6 to 1.2 mg/dL for males and 0.5 to 1.1 mg/dL for females. Serum creatinine is a waste product from the normal breakdown of muscle tissue. As kidneys become impaired for any reason, the serum creatinine level rises due to poor clearance by the kidneys.

Choice B reason: A GFR below 60 mL/min/1.73 m for three months or more is one of the criteria for the diagnosis of chronic kidney disease. GFR is a measure of how well the kidneys filter blood, and a lower GFR indicates poorer kidney function.

Choice C reason: Blood urea nitrogen (BUN) levels should indeed be between 7 and 20 mg/dL. BUN measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. BUN levels can rise with the level of protein in your diet and your kidney function[^10^].

Choice D reason: An increase in serum potassium can indicate hyperkalemia, which may be a sign of acute kidney injury. Potassium is a critical electrolyte, and its levels are tightly regulated by the kidneys. High levels can lead to dangerous heart rhythms.

A. Transplant rejection B. Anaphylaxis C. Bacterial phagocytosis D. Hay fever allergy

Correct Answer is A

Explanation

Choice A reason: play a crucial role in transplant rejection. They can recognize and attack foreign tissues, including transplanted organs, leading to rejection. This immune response is a significant concern in transplant medicine, and managing T cell activity is essential for the success of organ transplants.

Choice B reason: While anaphylaxis is an acute allergic reaction, it is more commonly associated with the release of histamines and other mediators from mast cells and basophils. can contribute to the severity of the reaction, but they are not the primary cells involved in anaphylaxis.

Choice C reason: Bacterial phagocytosis is primarily the function of phagocytes like neutrophils and macrophages. do not directly engage in phagocytosis but can activate other immune cells that do.

Choice D reason: Hay fever, or allergic rhinitis, involves an immune response to airborne allergens, with contributing to the development of symptoms by helping to produce IgE antibodies. However, the immediate symptoms of hay fever are more directly related to mast cell activation rather than activity.
