HESI Medical Surgical Exam
1. A client who has developed acute kidney injury (AKI) due to an aminoglycoside antibiotic has moved from the oliguric phase to the diuretic phase of AKI. Which parameters are most important for the nurse to plan to carefully monitor?
- A. Side effects of total parenteral nutrition (TPN) and Intralipids.
- B. Uremic irritation of mucous membranes and skin surfaces.
- C. Elevated creatinine and blood urea nitrogen (BUN).
- D. Hypovolemia and electrocardiographic (ECG) changes.
Correct answer: D
Rationale: During the diuretic phase of acute kidney injury (AKI), monitoring for hypovolemia and electrocardiographic (ECG) changes is crucial. Hypovolemia can occur due to the increased urine output in this phase, potentially leading to dehydration and electrolyte imbalances. Electrolyte imbalances can result in ECG changes, such as arrhythmias, which can be life-threatening. Therefore, careful monitoring of fluid status and ECG findings helps in preventing complications. Choices A, B, and C are not the most crucial parameters to monitor during the diuretic phase of AKI. Side effects of total parenteral nutrition (TPN) and Intralipids, uremic irritation of mucous membranes and skin surfaces, and elevated creatinine and blood urea nitrogen (BUN) are important considerations in other phases of AKI or in other conditions, but they are not the primary focus during the diuretic phase when hypovolemia and ECG changes take precedence.
2. A client presents to the clinic with concerns about her left breast. Which assessment finding is most important for the nurse to report?
- A. Multiple firm, round, freely movable masses.
- B. A slight asymmetry of the breasts.
- C. A fixed nodular mass with dimpling of the skin.
- D. Bloody discharge from the nipple.
Correct answer: C
Rationale: The correct answer is C. A fixed nodular mass with dimpling of the skin is concerning for malignancy, such as breast cancer, and should be reported immediately for further evaluation. This finding is more suspicious compared to multiple firm, round, freely movable masses (choice A), which could be benign breast lumps. A slight asymmetry of the breasts (choice B) is a common finding and not as alarming as a fixed nodular mass with dimpling of the skin. Bloody discharge from the nipple (choice D) can be suggestive of other conditions like intraductal papilloma but is not as urgent as the finding described in choice C.
3. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:
- A. Zygote
- B. Blastomere
- C. Morula
- D. Blastocyst
Correct answer: C
Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'
4. A female client with Cushing's syndrome is admitted to the medical-surgical unit. During the admission assessment, Nurse Tyzz notes that the client is agitated, irritable, has poor memory, reports loss of appetite, and appears disheveled. These findings are consistent with which problem?
- A. Depression
- B. Neuropathy
- C. Hypoglycemia
- D. Hyperthyroidism
Correct answer: A
Rationale: The correct answer is A: Depression. Depression is a common psychological manifestation in clients with Cushing's syndrome. In this scenario, the client's symptoms of agitation, irritability, poor memory, loss of appetite, and disheveled appearance are indicative of depressive symptoms rather than neuropathy, hypoglycemia, or hyperthyroidism. Neuropathy typically presents with sensory changes and motor deficits, which are not described in the scenario. Hypoglycemia would manifest with symptoms such as diaphoresis, tremors, and confusion, which are not mentioned. Hyperthyroidism symptoms include weight loss, heat intolerance, and palpitations, which are not consistent with the client's presentation.
5. The RN is admitting a male client who takes lithium carbonate (Eskalith) twice a day. Which information should the RN report to the HCP immediately?
- A. Short-term memory loss.
- B. Five-pound weight gain.
- C. Decreased affect.
- D. Nausea and vomiting.
Correct answer: D
Rationale: Nausea and vomiting are signs of potential lithium toxicity, which is a serious condition requiring immediate attention. These symptoms can indicate a dangerous level of lithium in the body that can lead to severe complications. Short-term memory loss (A), five-pound weight gain (B), and decreased affect (C) are important to monitor but are not as immediately concerning as symptoms of potential toxicity like nausea and vomiting.
