Question 1 of 9

Sara S. is a 41-year-old patient who has just had a bone marrow transplant. The AGACNP knows that which medication will be used to decrease her risk of graft-versus-host reaction?

Correct Answer: B

Rationale: The correct answer is B: Cyclosporine. Cyclosporine is an immunosuppressant medication commonly used post-bone marrow transplant to prevent graft-versus-host disease. It works by inhibiting T-cell activation and proliferation, reducing the risk of the donor's immune cells attacking the recipient's tissues. Immune globulin (A) is used for passive immunization, not prevention of graft-versus-host reaction. Prophylactic antibiotics (C) are used to prevent infections post-transplant, not graft-versus-host disease. Systemic corticosteroids (D) may be used to treat graft-versus-host disease but are not the first-line prophylactic medication.

Question 2 of 9

The baby dies immediately after birth due to the presence of

Correct Answer: C

Rationale: The correct answer is C: Truncus arteriosus. In this condition, there is a single large vessel arising from the heart that gives rise to the systemic, pulmonary, and coronary arteries. This results in mixing of oxygenated and deoxygenated blood, leading to severe cyanosis and inadequate oxygenation of the body, causing immediate death after birth. A: Pulmonary stenosis and B: Aortic coarctation typically do not cause immediate death after birth. D: Ductus arteriosus is a normal fetal structure that closes shortly after birth and its presence would not directly cause immediate death.

Question 3 of 9

A patient who has been in the intensive care unit for 17 days develops hyponatremic hyperosmolality. The patient weighs 132 lb (59.9 kg), is intubated, and is receiving mechanical ventilation. The serum osmolality is 320 mOsmL kg H2O. Clinical signs include tachycardia and hypotension. The adult-gerontology acute care nurse practitioners initial treatment is to

Correct Answer: B

Rationale: The correct answer is B: reduce serum sodium concentration by infusing a 0.45% sodium chloride solution. In hyponatremic hyperosmolality, the primary goal is to correct the low serum sodium levels. A 0.45% sodium chloride solution is hypotonic, which helps to slowly correct the serum sodium concentration without causing rapid shifts in osmolality. Infusing a hypotonic solution will gradually increase the serum sodium levels, addressing the underlying issue. Choices A, C, and D are incorrect because they do not directly address the low serum sodium levels, which is essential in treating hyponatremic hyperosmolality. Infusing a 5% dextrose in 0.2% sodium chloride solution (Choice A) or a 5% dextrose in water solution (Choice D) would not correct the low sodium levels. Replenishing volume with a 0.9% sodium chloride solution (Choice C) would not directly

Question 4 of 9

Haematinics, dietary advice, and close surveillance are management plans for

Correct Answer: A

Rationale: The correct answer is A: Moderate anaemia. Haematinics, dietary advice, and close surveillance are appropriate management plans for moderate anaemia to improve iron levels and overall health. For mild anaemia, dietary changes alone may be sufficient. Severe anaemia often requires more aggressive treatments like blood transfusions. Anaemia prevention focuses on strategies to avoid developing anaemia rather than managing an existing case.

Question 5 of 9

When a hand or foot lies alongside the presenting part, the presentation is said to be

Correct Answer: D

Rationale: The correct answer is D: Compound. In compound presentation, a hand or foot is alongside the presenting part, usually the head. This can complicate the delivery process. A: Footling presentation means the foot presents first. B: Transverse presentation is when the baby is lying sideways. C: Cephalic presentation is normal, with the head presenting first. In this scenario, D is the correct answer as it specifically describes the situation where a hand or foot is alongside the presenting part.

Question 6 of 9

Positive fasting blood sugar and oral glucose tolerance test, as well as being symptomatic, is diagnostic of

Correct Answer: B

Rationale: The correct answer is B, Gestational diabetes mellitus. This condition is diagnosed when a pregnant woman exhibits symptoms of diabetes and has elevated fasting blood sugar and abnormal oral glucose tolerance test results. This specific combination of symptoms and test results during pregnancy points towards gestational diabetes mellitus. A: Potential diabetes mellitus - Incorrect. The symptoms combined with abnormal test results suggest an active condition, not potential. C: Clinical diabetes mellitus - Incorrect. While the symptoms and test results indicate diabetes, the context of pregnancy suggests gestational diabetes. D: Chemical diabetes mellitus - Incorrect. This term is not commonly used in medical practice and does not specifically address the condition in the given scenario.

Question 7 of 9

K. T. presents for a routine wellness examination, and the review of systems is significant only for a markedly decreased capacity for intake and a vague sense of nausea after eating. K. T. denies any other symptoms the remainder of the GI review of systems is negative. His medical history is significant for complicated peptic ulcer disease that finally required resection for a perforated ulcer. The AGACNP advises the patient that

Correct Answer: D

Rationale: The correct answer is D: His symptoms occur in 5 to 10% of people after ulcer surgery. This is the correct answer because the patient's symptoms of decreased capacity for intake and nausea after eating are common post-operative complications following ulcer surgery. By stating this fact to the patient, the AGACNP is providing reassurance that these symptoms are not unusual. Explanation for why the other choices are incorrect: A: Endoscopy is not necessary at this point since the symptoms described by the patient are known post-operative complications and do not indicate an urgent need for endoscopy. B: While gastroparesis can be a complication of ulcer surgery, there is no information in the case to suggest that the patient has chronic gastroparesis. C: Jumping to the conclusion that medication is unlikely to help and another surgery may be needed is premature and not supported by the information provided in the case.

Question 8 of 9

Which of the following statements is true with respect to adrenal tumors that produce gender symptoms?

Correct Answer: D

Rationale: The correct answer is D because virilizing adrenal tumors are more likely to be malignant in children. This is due to the fact that virilizing tumors can be associated with conditions like adrenocortical carcinoma, which is a malignant tumor. In contrast, feminizing adrenal tumors are not always carcinomas (choice A) and are not the most common type of adrenal tumor (choice B). Additionally, virilizing tumors in women can be localized to different parts of the adrenal gland, not just the cortex (choice C). Therefore, choice D is the most accurate statement among the options provided.

Question 9 of 9

When a hand/foot lies alongside the presenting part, the presentation is said to be

Correct Answer: C

Rationale: The correct answer is C: Compound. When a hand or foot lies alongside the presenting part during childbirth, it is called a compound presentation. This can be a complication as it increases the risk of the presenting part not fitting through the birth canal properly. A: Footling presentation occurs when the baby's foot or feet are the first to emerge from the birth canal. B: Transverse presentation is when the baby is lying sideways in the uterus. D: Cephalic presentation is the ideal position for vaginal delivery, with the baby's head down and ready to be born.
