A patient is suffering from ketoacidosis caused by an unregulated high protein diet.
Which function of the blood has been compromised?
Stabilizing fluid distribution in the body.
Stabilizing the body's pH.
Protecting against microorganisms.
Transporting nutrients.
Transporting hormones.
The Correct Answer is B
Choice B rationale
Ketoacidosis results from the excessive production of ketone bodies, which are acidic. A high protein diet, if not balanced, can lead to increased amino acid catabolism, generating more acidic byproducts. The blood's ability to buffer these acids and maintain a stable pH (normal blood pH: 7.35-7.45) is compromised, leading to metabolic acidosis.
Choice A rationale
Stabilizing fluid distribution is primarily a function of plasma proteins, particularly albumin, which contribute to colloid osmotic pressure, and the kidneys' regulation of water and electrolyte balance. While severe acidosis can affect fluid shifts, the primary compromise in ketoacidosis relates to pH balance.
Choice C rationale
Protecting against microorganisms is a function of white blood cells (leukocytes) and antibodies (immunoglobulins) present in the blood. While severe metabolic disturbances can indirectly impact immune function over time, the immediate and direct compromise in ketoacidosis is related to acid-base balance.
Choice D rationale
Transporting nutrients, such as glucose, amino acids, and lipids, is a fundamental function of blood. While metabolic imbalances due to ketoacidosis affect nutrient utilization, the core ability of blood to physically transport these substances is not the primary function compromised.
Choice E rationale
Transporting hormones is a crucial endocrine function of the blood, allowing hormones to reach their target cells. While hormonal imbalances can contribute to ketoacidosis (e.g., insulin deficiency), the direct compromise of blood's ability to transport hormones is not the central issue in ketoacidosis itself.

Correct Answer is D
Explanation
Choice A rationale
The mitral valve is between the left atrium and left ventricle. The pulmonary valve is between the right ventricle and the pulmonary artery. Therefore, the mitral valve opening and pulmonary valve closing do not directly correlate with left ventricular contraction in this manner.
Choice B rationale
The right AV valve (tricuspid valve) is located between the right atrium and right ventricle. When the left ventricle contracts, it is not directly involved with the right AV valve or the pulmonary valve in this specific coordinated sequence.
Choice C rationale
The right AV valve (tricuspid valve) is in the right side of the heart, controlling blood flow from the right atrium to the right ventricle. The aortic valve is on the left side of the heart. These two valves do not coordinate in this manner during left ventricular contraction.
Choice D rationale
When the left ventricle contracts during systole, the pressure within the ventricle rises. This increased pressure pushes open the aortic valve, allowing blood to be ejected into the aorta. Simultaneously, the increased ventricular pressure forces the mitral (bicuspid) valve to close, preventing blood from flowing backward into the left atrium.
Correct Answer is A
Explanation
Choice A rationale
Vaccination works by introducing attenuated (weakened) or inactivated forms of pathogens, or specific pathogen components (antigens), into the body. This exposure triggers the immune system to mount a primary immune response, leading to the production of antibodies and memory cells without causing the actual disease, thus providing future protection.
Choice B rationale
Antibiotics are antimicrobial drugs that directly kill or inhibit the growth of bacteria. They are not involved in stimulating the body's immune system for long-term immunity; instead, they provide a direct therapeutic intervention against bacterial infections.
Choice C rationale
Vaccination aims to increase the body's resistance to disease, not its susceptibility. By priming the immune system with harmless forms of pathogens, vaccines enhance the body's ability to quickly and effectively combat future infections, thereby reducing susceptibility.
Choice D rationale
Vaccination does not suppress the immune system's natural response; rather, it activates and enhances it. The purpose of a vaccine is to stimulate a controlled immune response that leads to the development of immunological memory, preparing the immune system for real pathogen exposure.
