A patient presents with watery diarrhea, abdominal cramps, and nausea after consuming contaminated water from a stream during a camping trip. Laboratory tests reveal oocysts in the stool sample. Which of the following parasites is most likely responsible for this infection?

Correct Answer: C

Rationale: Cryptosporidium parvum is a protozoan parasite often found in contaminated water sources. This parasite is known to cause watery diarrhea, abdominal cramps, and nausea in infected individuals. The presence of oocysts in the stool sample is characteristic of Cryptosporidium infection. Other parasitic infections may present with similar symptoms, but in this case, the most likely culprit based on the exposure history and laboratory findings is Cryptosporidium parvum.

Correct Answer: D

Rationale: Pemoline (Cylert) is a central nervous system stimulant used in the treatment of ADHD. One of the significant potential side effects of pemoline is hepatotoxicity, which can manifest as elevated liver function test results. Therefore, the nurse must monitor the patient's liver function regularly while they are taking pemoline to monitor for any signs of liver damage or dysfunction. It is essential to educate the patient about the signs and symptoms of liver problems, such as jaundice (yellowing of the skin or eyes), abdominal pain, nausea, or dark urine, and to report any such symptoms immediately to their healthcare provider. Regular monitoring and early detection of liver function abnormalities can help prevent severe liver damage in patients taking pemoline.

Correct Answer: B

Rationale: In this scenario, the firm and midline fundus at three hours postpartum indicates that the uterus is contracting well. The presence of a small constant trickle of blood on perineal inspection suggests ongoing bleeding. This combination of findings is concerning for retained placenta, where a portion of the placenta remains attached to the uterine wall and prevents proper contraction and closure of the blood vessels at the placental site. Retained placenta can lead to postpartum hemorrhage and requires prompt evaluation and intervention to prevent complications. Nurse Kayla should escalate this finding to the healthcare provider for further assessment and management.

Correct Answer: C

Rationale: When a pregnant woman is diagnosed with preeclampsia, the focus of health care shifts to the individual woman herself. Preeclampsia is a serious condition that affects the health of the pregnant woman and her unborn child. The healthcare team will prioritize the care and treatment of the woman to ensure her well-being and safety. In this scenario, the emphasis is on providing personalized and targeted care to address the needs of the individual patient, rather than a broader focus on population groups, communities, or families.

Correct Answer: C

Rationale: The correct response for the nurse in this situation would be to offer the victim a shower after evidence is collected. It is essential to preserve any physical evidence that may be present from the assault during the forensic examination. Allowing the victim to shower before evidence is collected could potentially compromise the evidence and hinder the investigation. The nurse should provide support to the victim during this difficult time and assure them that they will have the opportunity to shower once the necessary evidence is obtained. It is also crucial for the nurse to offer empathy and understanding while explaining the importance of preserving any evidence related to the assault.

Correct Answer: A

Rationale: The health care team will try the oral route first for Ms. C for delivering nutrition and fluid because it is the most natural and least invasive method. If the patient is able to tolerate oral intake and has adequate oral intake, it is typically the preferred route. Only if she is unable to meet her nutritional needs orally or has difficulty swallowing, then alternative routes such as nasogastric tube, gastrostomy tube, or intravenous routes may be considered. It's important to promote oral intake whenever possible to maintain the patient's quality of life and prevent complications associated with more invasive methods.

Correct Answer: B

Rationale: The patient's presentation of well-demarcated, erythematous plaques with silvery scales on the trunk and extensor surfaces of the limbs is classic for psoriasis. Additionally, the family history of similar skin lesions further supports the diagnosis of psoriasis, as it is a condition with a genetic predisposition. Pityriasis rosea typically presents with a herald patch followed by oval, scaly lesions in a Christmas tree pattern. Erythema multiforme is characterized by target-like lesions. Lichen planus presents as purple, polygonal, flat-topped papules that may have fine white lines on their surface known as Wickham striae.

Correct Answer: D

Rationale: Cromolyn sodium (nasal crom) is a mast cell stabilizer that is commonly used to prevent symptoms of allergic rhinitis, such as sneezing, itching, and congestion. It works best when used before exposure to allergens. The most effective administration schedule for nasal crom is to start using it just after allergy symptoms begin, with a dose of twice-a-day. This helps to prevent the release of histamine and other inflammatory substances from mast cells, thereby reducing allergic symptoms. Using nasal crom in this way can help provide relief and improve the overall management of allergic rhinitis.
