The nurse is providing care for four patients: Patient A, diagnosed with emphysema and has an oxygen saturation of 94% on room air; Patient B, who is postoperative with a hemoglobin level of 8.2 mg/dL (82 g/L); Patient C, newly admitted with a potassium level of 3.8 mEq/L (3.8 mmol/L); and Patient D, who is scheduled for an appendectomy and has a white blood cell (WBC) count of 14,000 mm² (14 x 10°/L). What action should the nurse take next?
Transfer Patient D to an isolation room 24 hours prior to surgery.
Increase Patient A’s oxygen to 4 L/minute via nasal cannula.
Ensure that there are two units of packed cells available for Patient B.
Request the dietitian to include a banana in Patient C’s breakfast tray.
The Correct Answer is C
Choice A rationale
There is no indication that Patient D, who is scheduled for an appendectomy and has a white blood cell (WBC) count of 14,000 mm² (14 x 10°/L), needs to be transferred to an isolation room 24 hours prior to surgery.
Choice B rationale
Patient A, diagnosed with emphysema and has an oxygen saturation of 94% on room air, does not necessarily need an increase in oxygen. An oxygen saturation of 94% is within normal limits.
Choice C rationale
Patient B, who is postoperative with a hemoglobin level of 8.2 mg/dL (82 g/L), may require a blood transfusion. A hemoglobin level of 8.2 mg/dL is low, and having packed cells available is a prudent measure.
Choice D rationale
Patient C, newly admitted with a potassium level of 3.8 mEq/L (3.8 mmol/L), has a normal potassium level. Including a banana in the breakfast tray is not a priority.

Correct Answer is D
Explanation
Choice A rationale
While it’s true that many contraceptives can help prevent certain sexually transmitted infections (STIs), they are not 100% effective. Condoms, for instance, can reduce the risk of STIs that are spread through bodily fluids, such as gonorrhea and chlamydia. However, they are less effective at protecting against STIs that are transmitted through skin-to-skin contact, such as herpes and human papillomavirus (HPV)1.
Choice B rationale
Not all STIs are transmitted through sexual intercourse. Some STIs, such as herpes and HPV, can be spread through skin-to-skin contact. Others, like HIV and hepatitis B and C, can also be spread through sharing needles or from mother to child during childbirth.
Choice C rationale
Safe sex practices can significantly reduce, but not completely remove, the risk of STIs. These practices include using condoms correctly every time you have sex, getting tested regularly for STIs, and limiting the number of sexual partners.
Choice D rationale
Reinfections can indeed occur from having sex with untreated partners. This is particularly true for bacterial STIs like syphilis. If a person’s partner is not treated, the bacteria can remain in their body and they can pass the infection back to the person after they’ve been treated.
Correct Answer is A
Explanation
Choice A rationale
The patient’s history of asthma, previous hospitalizations for asthma-related symptoms, and the current presentation of difficulty breathing and wheezing suggest that she is likely experiencing an asthma exacerbation related to environmental factors. Asthma is a chronic condition that can cause symptoms such as wheezing, shortness of breath, and chest tightness, which the patient is currently experiencing. Environmental factors such as allergens, air pollution, and changes in weather can trigger asthma symptoms.
Choice B rationale
While smoking is a major risk factor for COPD, the patient denies smoking. Additionally, COPD is more common in older adults, and the patient is only 22 years old. Therefore, it is less likely that her symptoms are due to COPD.
Choice C rationale
Pneumonia is typically associated with additional symptoms such as fever, cough with phlegm, and chest pain. The patient’s symptoms do not align with a typical presentation of pneumonia.
Choice D rationale
Tuberculosis is a bacterial infection that typically presents with a chronic cough, weight loss, and night sweats. The patient’s symptoms do not align with a typical presentation of tuberculosis.
