Nursing Elites

1. Where is the cervix located?

• A. Top of the uterus
• B. Top of the ovaries
• C. Bottom of the vagina
• D. Bottom of the uterus

Correct answer: D

Rationale: The cervix is located at the bottom of the uterus, where it opens into the vagina. It serves as the passageway between the uterus and the vagina, playing a crucial role in childbirth and menstrual flow. Choice A ('Top of the uterus') is incorrect because the cervix is not located at the top of the uterus. Choice B ('Top of the ovaries') is incorrect as the cervix is not located near the ovaries. Choice C ('Bottom of the vagina') is incorrect as the cervix is not located at the bottom of the vagina, but rather at the bottom of the uterus.

2. Which term refers to a position farther from the midline of the body? For example, the little toe is lateral to the big toe on the same foot.

• A. Lateral
• B. Medial
• C. Proximal
• D. Distal

Correct answer: A

Rationale: The correct answer is A: Lateral. Lateral refers to a position farther away from the midline of the body. In the example provided, the little toe is indeed lateral to the big toe on the same foot. This is in contrast to 'medial,' which means closer to the midline. 'Proximal' refers to a position closer to the point of attachment or the trunk of the body, while 'distal' refers to a position farther from the point of attachment or the trunk of the body.

3. Two nursing students will be completing a scientific experiment measuring the mass of chewed gum after one-minute chewing increments. Which lab equipment will the students most likely use?

• A. Triple beam balance
• B. Anemometer
• C. Hot plate
• D. Microscope

Correct answer: A

Rationale: The correct answer is A: Triple beam balance. A triple beam balance is the most suitable lab equipment for measuring mass accurately, which is necessary for this experiment. An anemometer measures wind speed, a hot plate is used for heating substances, and a microscope is used for magnifying objects, none of which are relevant to measuring the mass of chewed gum.

4. In a covalent bond, the shared electrons:

• A. Are completely transferred to one atom.
• B. Spend more time closer to the more electronegative atom.
• C. Remain equidistant between the two atoms.
• D. Do not influence the bond strength.

Correct answer: B

Rationale: In a covalent bond, the shared electrons spend more time closer to the more electronegative atom. Electronegativity is the ability of an atom to attract electrons in a chemical bond. The more electronegative atom exerts a stronger pull on the shared electrons, causing them to be closer to that atom. Choice A is incorrect because in a covalent bond, electrons are shared, not completely transferred. Choice C is incorrect as the shared electrons are not equidistant but are closer to one atom due to electronegativity differences. Choice D is incorrect because shared electrons play a significant role in determining the bond strength by the strength of the bond formed through electron sharing.

5. Identify the organ responsible for blood filtration.

• A. Liver
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys are the organs responsible for blood filtration in the human body. They filter waste products and excess substances from the blood to produce urine. The liver is primarily involved in detoxification and metabolism, the spleen functions in immune responses and blood storage, and the pancreas aids in digestion and blood sugar regulation. Therefore, choices A, C, and D are incorrect as they do not primarily serve the function of blood filtration.
