Nursing Metric Conversions

1. How many millimeters are in 1 centimeter?

Correct answer: B

Rationale: The correct answer is B: '10 mm'. There are 10 millimeters in 1 centimeter. To convert centimeters to millimeters, you multiply by 10 because 1 centimeter is equivalent to 10 millimeters. Choice A '1 mm' is incorrect as it represents the size of 1 millimeter, not the conversion from centimeters to millimeters. Choice C '100 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter. Choice D '1,000 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter.

2. The adaptive immune system has two main branches: humoral and cell-mediated immunity. Which type of immune cell is primarily responsible for antibody production?

Correct answer: C

Rationale: B cells are primarily responsible for antibody production in the adaptive immune system. When activated, B cells differentiate into plasma cells, which are specialized to produce antibodies. Helper T cells play a crucial role in activating B cells, but they do not directly produce antibodies. Cytotoxic T cells are involved in cell-mediated immunity by killing infected cells, while natural killer cells are part of the innate immune system and target virus-infected and cancerous cells. Therefore, the correct answer is C (B cells) as they are directly involved in the production of antibodies, essential for humoral immunity.

3. Which of the following defines the word 'unilateral'?

Correct answer: A

Rationale: The correct answer is A: 'Performed by one person.' 'Unilateral' means something done by one person or group without the agreement of another. Choice B is incorrect as it suggests the opposite of what 'unilateral' means. Choice C is incorrect as it does not capture the essence of 'unilateral.' Choice D is incorrect as it is not directly related to the definition of 'unilateral.'

4. During a healthy heartbeat, the P wave on an ECG represents

Correct answer: D

Rationale: The P wave on an ECG represents the depolarization of the atria. This electrical activity initiates the contraction of the atria, allowing blood to be pumped into the ventricles. The P wave is the first positive deflection seen on the ECG and signifies the beginning of atrial depolarization, which is a critical step in the cardiac cycle. Choices A, B, and C are incorrect. Option A (The repolarization of the ventricles) is represented by the T wave on the ECG. Option B (The electrical conduction through the AV node) is not represented by the P wave but rather by the PR interval on the ECG. Option C (The contraction phase of the ventricles (systole)) is more related to the QRS complex on the ECG, which represents ventricular depolarization and contraction.

5. Which of the following examples is a compound-complex sentence?

Correct answer: D

Rationale: Sentence D is a compound-complex sentence because it contains two independent clauses ('Even though the puppy was much smaller than his mother' and 'his eyes were dark brown and shiny just like hers') and one dependent clause ('and his ears were long and floppy, too'). Choices A, B, and C do not meet the criteria for a compound-complex sentence as they lack a combination of independent and dependent clauses.
