English Grammar

1. What is the main function of transition words and phrases in writing?

A. To add unnecessary embellishments and fluff.
B. To emphasize specific words or phrases in the text.
C. To connect ideas smoothly and guide the reader's flow.
D. To introduce opposing viewpoints and counterarguments.

Correct answer: C

Rationale: Transition words and phrases bridge ideas, create logical flow, and enhance the coherence of your writing.

2. Dendrites are finger-like extensions found on

A. Muscle cells
B. Connective tissue cells
C. Neurons
D. Epithelial cells

Correct answer: C

Rationale: Dendrites are the primary sites for receiving signals in a neuron. They are specialized extensions that branch out from the cell body of a neuron to receive incoming information from other neurons. These finger-like projections play a crucial role in transmitting electrical impulses and communication within the nervous system. Muscle cells, connective tissue cells, and epithelial cells do not have dendrites as they are not involved in neuronal communication.

3. Which of the following is the main function of the skin?

A. To protect the body from harm
B. To regulate body temperature
C. To produce hormones
D. To sense touch, temperature, and pain

Correct answer: A

Rationale: Rationale: A) To protect the body from harm: The skin acts as a physical barrier that protects the body from external threats such as pathogens, UV radiation, and physical injuries. It helps prevent infections and dehydration, making it a crucial function of the skin. B) To regulate body temperature: While the skin does play a role in regulating body temperature through processes like sweating and vasodilation/vasoconstriction, its primary function is protection. C) To produce hormones: Hormone production is primarily carried out by endocrine glands such as the pituitary gland, thyroid gland, and adrenal glands, not the skin. D) To sense touch, temperature, and pain: The skin contains sensory receptors that allow us to perceive touch, temperature, and pain, but this function is secondary to its main role of protecting the body from harm.

4. A medication order is for 250 micrograms of a drug to be administered subcutaneously. The available syringe measures in milliliters. How many milliliters should the nurse draw up?

A. 0.00025 milliliters
B. 0.0025 milliliters
C. 0.025 milliliters
D. 0.25 milliliters

Correct answer: B

Rationale: First convert micrograms to milliliters, knowing 1000 micrograms equal 1 milliliter. Divide the desired dosage (250 micrograms) by the conversion factor (1000 micrograms/milliliter) to find the volume needed: 250 micrograms / 1000 micrograms/milliliter = 0.00025 milliliters. However, drawing such a small volume might be inaccurate, so round to the nearest practical measurement, which is 0.0025 milliliters.

5. The lymphatic system works closely with which other body system to fight infections?

A. Respiratory system
B. Digestive system
C. Immune system
D. Nervous system

Correct answer: A

Rationale: The correct answer is the Respiratory system. The lymphatic system and the respiratory system work closely together to fight infections. The respiratory system helps to filter out pathogens and other harmful substances from the air we breathe, while the lymphatic system produces and transports white blood cells (lymphocytes) that play a key role in the immune response against infections. This collaboration helps the body to defend against respiratory infections and maintain overall health.
