1. The healthcare provider calculates the IV flow rate for a patient receiving lactated Ringer's solution. The patient needs to receive 2000mL of Lactated Ringer's over 36 hours. The IV infusion set has a drop factor of 15 drops per milliliter. How many drops per minute should the healthcare provider set the IV to deliver?

• A. 8
• B. 10
• C. 14
• D. 18

Correct answer: C

Rationale: To determine the drops per minute, we use the formula Drops Per Minute = (Milliliters x Drop Factor) / Time in Minutes. In this case, Drops Per Minute = (2000mL x 15 drops/mL) / (36 hours x 60 minutes/hour) = 30000 / 2160 = 13.89 (approximately 14). Therefore, the correct answer is 14 drops per minute. Choice A (8), Choice B (10), and Choice D (18) are incorrect as they do not correctly calculate the drops per minute based on the given information.

2. A systolic blood pressure of 145 mm Hg is classified as:

• A. Normotensive
• B. Prehypertension
• C. Stage I hypertension
• D. Stage II hypertension

Correct answer: C

Rationale: A systolic blood pressure of 145 mm Hg falls within the range of 140-159 mm Hg, which is classified as Stage I hypertension. Normotensive individuals have a systolic blood pressure less than 120 mm Hg, making choice A incorrect. Prehypertension is characterized by a systolic blood pressure ranging from 120-139 mm Hg, excluding choice B. Stage II hypertension is diagnosed when the systolic blood pressure is greater than 160 mm Hg, making choice D incorrect. Therefore, the correct classification for a systolic blood pressure of 145 mm Hg is Stage I hypertension.

3. A patient has come into the emergency room after an injury at work in which their upper body was pinned between two pieces of equipment. The nurse notes bruising in the upper abdomen and chest. The patient is complaining of sharp chest pain, having difficulty breathing, and their trachea is deviated to the left side. Which of the following conditions are these symptoms most closely associated with?

• A. Left-sided pneumothorax
• B. Pleural effusion
• C. Atelectasis
• D. Right-sided pneumothorax

Correct answer: D

Rationale: The patient is most likely suffering from a right-sided pneumothorax. Symptoms of a pneumothorax include sharp chest pain, difficulties with breathing, decreased vocal fremitus, absent breath sounds, and tracheal shift to the opposite of the affected side. In this case, the patient's trachea is deviated to the left side, indicating a right-sided pneumothorax. Choices A, B, and C can be eliminated as they do not present with the specific symptoms described in the scenario. Left-sided pneumothorax would not cause tracheal deviation to the left side. Pleural effusion typically presents with dull chest pain and decreased breath sounds, not sharp chest pain and tracheal deviation. Atelectasis would not cause tracheal deviation and is more associated with lung collapse rather than air accumulation in the pleural space.

4. A 34-year-old female has recently been diagnosed with an autoimmune disease. She has also recently discovered that she is pregnant. Which of the following is the only immunoglobulin that will provide protection to the fetus in the womb?

• A. IgA
• B. IgD
• C. IgE
• D. IgG

Correct answer: D

Rationale: IgG is the only immunoglobulin that can cross the placental barrier, providing passive immunity to the fetus. About 70-80% of the immunoglobulins in the blood are IgG. Specific IgG antibodies are generated after an initial exposure to an antigen, offering long-term protection against microorganisms. IgG antibodies are critical for protecting the fetus as they can be rapidly reproduced upon re-exposure to the same antigen. IgA is primarily found in mucosal areas, IgD is involved in antigen recognition, and IgE is associated with allergic reactions, but they do not provide the same level of protection to the fetus as IgG.

5. The patient is being taught about pulmonary function testing (PFT). Which statement made by the patient indicates effective teaching?

• A. I will use my inhaler right before the test.
• B. I won't eat or drink anything 8 hours before the test.
• C. I should inhale deeply and blow out as hard as I can during the test.
• D. My blood pressure and pulse will be checked every 15 minutes after the test.

Correct answer: C

Rationale: The correct answer is 'I should inhale deeply and blow out as hard as I can during the test.' This statement indicates effective teaching because for PFT, the patient needs to inhale deeply and exhale forcefully. This maneuver helps in assessing lung function accurately. Choices A, B, and D are incorrect. Using an inhaler right before the test may alter the test results, which is not recommended. Fasting for 8 hours is not necessary for a PFT, and checking blood pressure and pulse every 15 minutes after the test is not part of the PFT procedure.
