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 that commonly causes waterborne illness characterized by watery diarrhea, abdominal cramps, and nausea. This parasite is often transmitted through contaminated water sources such as streams or lakes. Laboratory tests identifying oocysts in the stool sample are indicative of Cryptosporidium infection. Giardia lamblia can also cause similar symptoms, but the presence of oocysts points more towards Cryptosporidium in this case. Entamoeba histolytica causes amoebic dysentery with bloody diarrhea and is usually associated with fecal-oral transmission through contaminated food or water. Cyclospora cayetanensis typically causes prolonged watery diarrhea and is associated with the ingestion of contaminated food or water.

Correct Answer: D

Rationale: Prinzmetal's angina, also known as variant angina, is characterized by episodes of chest pain that occur at rest and are relieved by nitroglycerin. Patients with Prinzmetal's angina may also have transient ST-segment elevation on an electrocardiogram (ECG) during episodes of chest pain. This is due to coronary artery vasospasm, which causes temporary obstruction of blood flow to the heart muscle. Stable angina typically presents with chest pain on exertion that resolves with rest, while unstable angina and acute myocardial infarction present with chest pain that is not relieved with nitroglycerin and are associated with more severe coronary artery disease.

Correct Answer: B

Rationale: The primary purpose of interdisciplinary collaboration in nursing practice is to improve communication and coordination of patient care. When healthcare providers from different disciplines work together as a team, they can share their unique perspectives, knowledge, and skills to develop comprehensive care plans that address all aspects of a patient's well-being. This collaborative approach helps ensure that the patient receives holistic and coordinated care, leading to better outcomes and patient satisfaction. Effective communication and coordination among team members also help prevent errors, reduce duplication of efforts, and promote efficient use of resources. Overall, interdisciplinary collaboration is essential for delivering high-quality, patient-centered care in healthcare settings.

Correct Answer: D

Rationale: When a woman in active labor demonstrates signs of cephalopelvic disproportion (CPD) with the fetal head failing to descend despite strong contractions, the nursing action that should be prioritized is to prepare for immediate instrumental delivery. CPD can lead to a prolonged and difficult labor, increasing the risks for both the mother and the fetus. In cases where the fetal head is not descending adequately and the mother's contractions are strong, instrumental delivery, like forceps or vacuum extraction, may be necessary to facilitate the safe delivery of the baby. It is important to act promptly to avoid potential complications associated with prolonged labor. Other actions, such as performing a pelvic exam, changing maternal positions, or administering oxytocin, may be considered but addressing the issue of CPD efficiently through instrumental delivery should take precedence in this scenario.

Correct Answer: C

Rationale: The symptoms of polyuria (excessive urination), polydipsia (excessive thirst), and polyphagia (excessive hunger) are classic signs of diabetes mellitus. In this case, the presence of hyperglycemia (high blood sugar) and glycosuria (glucose in the urine) further support the diagnosis of diabetes mellitus. Insulin deficiency or resistance in diabetes leads to impaired glucose utilization and excessive glucose in the bloodstream, causing the classic symptoms observed in the patient. Hyperthyroidism, hypothyroidism, and Cushing's syndrome do not typically present with the hallmark symptoms of polyuria, polydipsia, and polyphagia associated with uncontrolled diabetes mellitus.

Correct Answer: B

Rationale: When managing a conscious patient with a foreign object lodged in the eye, the appropriate action is to rinse the eye with sterile saline solution. This helps to flush out the foreign object and reduce the risk of further injury or infection. Attempting to remove the object with tweezers or applying pressure to the eyelid can potentially cause more harm to the eye. Placing a bandage over the affected eye is not beneficial in this situation as it does not address the presence of the foreign object. Rinsing the eye with sterile saline solution is the safest and most effective initial step to take in managing a foreign object lodged in the eye.

Correct Answer: D

Rationale: The "Rights of Medication Administration" include the following fundamental principles to ensure safe medication administration: right patient, right medication, right dosage, right route, right time, and right documentation. The price of the medication is not a part of these essential rights. These rights help to prevent medication errors and ensure that patients receive the correct medication in the correct way.

Correct Answer: C

Rationale: Children with ADHD often display hyperactive and impulsive behaviors, such as excessive running, climbing, and fidgeting. These behaviors are characteristic symptoms of the hyperactive-impulsive subtype of ADHD. Children with ADHD may struggle to sit still, have difficulty engaging in quiet activities, and often seem on the go. Therefore, the nurse would expect to see signs of excessive movement and restlessness in a child with ADHD.

Correct Answer: B

Rationale: The right to refuse treatment is a fundamental patient right. In this case, the physician ordering medications for the client to take at home without the client's input or agreement could possibly violate the client's right to refuse treatment. It is important for patients to have the autonomy to make decisions regarding their own treatment, especially when they are still weak and symptomatic. Patients should have the opportunity to discuss their treatment plan with their healthcare provider and express any concerns or preferences they may have.
