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 parasite commonly found in contaminated water sources such as streams or lakes. It causes an infection called cryptosporidiosis, which often presents with symptoms like watery diarrhea, abdominal cramps, and nausea. The oocysts of Cryptosporidium parvum can be identified in stool samples, making it the likely culprit in this scenario. Giardia lamblia, another common waterborne parasite, can also cause similar symptoms but is characterized by trophozoites rather than oocysts in stool samples. Entamoeba histolytica is associated with amoebic dysentery and does not typically present with watery diarrhea. Cyclospora cayetanensis is another parasite causing gastrointestinal symptoms but is not as commonly associated with contaminated water sources as Cryptosporidium parvum.

Correct Answer: C

Rationale: Insulin glargine (Lantus) is a long-acting insulin that is typically administered once daily at the same time each day to help maintain a steady level of insulin in the body. It is important to rotate injection sites within the same body region (such as the abdomen, thigh, or upper arm) to prevent lipodystrophy (lumpiness or dents in the skin) and to ensure consistent absorption of the insulin. Proper rotation of injection sites helps to prevent tissue damage and ensures optimal insulin absorption, improving the effectiveness of insulin therapy. It is not necessary to inject insulin glargine before meals, vigorously shake the vial, or administer it with a rapid-acting insulin.

Correct Answer: A

Rationale: The nurse should encourage the parents to relate to each twin individually to enhance the attachment process. Building a strong attachment between the parents and each twin individually is vital for their emotional and psychological development. By spending quality one-on-one time with each twin, the parents can foster a unique bond with them, which can positively impact their relationship and overall development. This approach also helps prevent favoritism and ensures that each twin receives the attention and care they need to thrive.

Correct Answer: A

Rationale: The Family Coping Index is a tool designed to assess the strategies that a family uses to deal with stressful situations. It focuses on how families manage and cope with stress and challenges, rather than solely on their interactions, health management, or health habits. By identifying the family's coping strategies, healthcare professionals can better understand the family dynamics and provide targeted support and interventions to help them navigate difficult circumstances.

Correct Answer: A

Rationale: The patient's sudden onset of severe vertigo, nausea, vomiting, and nystagmus following a recent upper respiratory tract infection is consistent with vestibular neuritis. Vestibular neuritis is characterized by acute onset vertigo, often severe, which is typically associated with nausea, vomiting, and nystagmus. The condition is thought to be caused by inflammation of the vestibular nerve, often viral in nature, which can occur following an upper respiratory tract infection. This inflammation leads to dysfunction of the vestibular system in the inner ear, resulting in the symptoms described. Benign paroxysmal positional vertigo (BPPV), characterized by brief episodes of vertigo triggered by specific head movements, is less likely in this case given the sudden onset of symptoms not triggered by head movements. Meniere's disease is characterized by recurrent episodes of vertigo accompanied by hearing loss, tinnitus, and a feeling of fullness

Correct Answer: B

Rationale: Proton pump inhibitors (PPIs) are commonly prescribed for conditions involving excessive stomach acid production, such as peptic ulcer disease. One of the potential adverse effects of PPIs, such as omeprazole or pantoprazole, is the risk of hypokalemia. Hypokalemia is a condition characterized by low levels of potassium in the bloodstream. Prolonged use of PPIs can inhibit the absorption of potassium in the intestines, leading to a decrease in potassium levels in the body. Hypokalemia can present with symptoms such as muscle weakness, fatigue, irregular heartbeat, and in severe cases, it can result in life-threatening complications like cardiac arrhythmias. Therefore, it is essential for the nurse to closely monitor the patient for signs and symptoms of hypokalemia while on PPI therapy, especially if the patient is at risk for developing electrolyte imbalances.

Correct Answer: D

Rationale: Factor V Leiden mutation is the most common inherited predisposition to venous thrombosis. In this condition, there is a specific mutation in the factor V gene (also known as factor V Leiden) that makes factor V resistant to inactivation by activated protein C. This resistance leads to excessive clot formation, increasing the risk of recurrent venous thrombosis like DVT and PE. Patients with Factor V Leiden mutation may have a history of recurrent unprovoked venous thrombosis at a young age. In comparison, antithrombin III deficiency, protein C deficiency, and protein S deficiency are other inherited thrombophilias that may increase the risk of venous thrombosis, but Factor V Leiden mutation is the most likely cause in this case based on the presentation of recurrent episodes without apparent provoking factors.

Correct Answer: B

Rationale: The stomach is responsible for producing hydrochloric acid and intrinsic factor. Hydrochloric acid helps in the breakdown of proteins during digestion, while intrinsic factor aids in the absorption of vitamin B12 in the small intestine. These two components are crucial for the proper functioning of the digestive system, particularly in breaking down food and absorbing essential nutrients. The liver is involved in bile production, the pancreas in the production of digestive enzymes, and the small intestine in nutrient absorption, but the specific functions related to hydrochloric acid and intrinsic factor are primarily attributed to the stomach.

Correct Answer: B

Rationale: Reviewing and comparing the findings with other researches on the same topic is done mainly by going back to the related literature and studies section of the study. This section provides a comprehensive overview of existing knowledge and research findings related to the topic being studied. By comparing the current findings with what has been previously discovered and reported by other researchers, Nurse Carmi can better analyze and interpret the results within the broader context of the existing body of knowledge. This helps in identifying the significance of the new findings, highlighting potential contributions to the field, and determining areas for further research or discussion.
