NCLEX RN Prioritization Questions

1. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?

A. Start an IV so contrast media may be given
B. Ensure that the patient has been NPO for at least 6 hours.
C. Inform radiology that a radioactive glucose preparation is needed
D. Instruct the patient to undress to the waist and remove any metal objects

Correct answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

2. Which fact about diabetes is true?

A. Only children get type 1 diabetes.
B. Only adults get type 2 diabetes.
C. Children and adults can have type 1 diabetes.
D. Both A and B

Correct answer: C

Rationale: The correct answer is that children and adults can have type 1 diabetes. Although type 1 diabetes is sometimes known as 'childhood diabetes,' it can affect individuals of any age. Type 1 diabetes is not limited to children. While type 2 diabetes is often associated with adults, children can also develop it, especially due to factors like obesity. Choices A and B are incorrect because diabetes is not exclusive to either children or adults; both types of diabetes can affect individuals across different age groups.

3. While caring for the client during the first hour after delivery, the nurse determines that the uterus is boggy and there is vaginal bleeding. What should be the nurse's first action?

A. Check vital signs.
B. Massage the fundus.
C. Offer a bedpan.
D. Check for perineal lacerations.

Correct answer: B

Rationale: The nurse's first action should be to massage the fundus until it is firm as uterine atony is the primary cause of bleeding in the first hour after delivery. Massaging the fundus helps to stimulate uterine contractions, which can help control the bleeding. Checking vital signs would be important but addressing the primary cause of bleeding takes precedence. Offering a bedpan is not a priority in this situation as the focus should be on managing the postpartum bleeding. Checking for perineal lacerations is also important but not the initial action needed to address the boggy uterus and vaginal bleeding.

4. 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.

5. A man is prescribed lithium to treat bipolar disorder. The nurse is most concerned about lithium toxicity when he notices which of these assessment findings?

A. The patient states he had a manic episode a week ago
B. The patient states he has been having diarrhea every day
C. The patient presents as severely depressed
D. The patient has a rash and pruritus on his arms and legs

Correct answer: B

Rationale: The correct answer is when the patient states he has been having diarrhea every day. Persistent diarrhea can lead to dehydration, which can increase the risk of lithium toxicity. The other options, such as a manic episode, severe depression, or rash and pruritus, are not directly associated with an increased risk of lithium toxicity.
