PN ATI Capstone Proctored Comprehensive Assessment 2020 A

Correct Answer: C

Rationale: The correct answer is C: Electrocardiogram. Amitriptyline can cause cardiac arrhythmias, so an electrocardiogram is necessary before starting treatment. A hearing examination (choice A) is not required before initiating amitriptyline. A glucose tolerance test (choice B) is not indicated for starting this medication. Pulmonary function tests (choice D) are not necessary before initiating amitriptyline for depression.

Correct Answer: A

Rationale: Tamoxifen is an antiestrogen medication used primarily in the treatment and prevention of breast cancer. It works by blocking the effects of estrogen in the breast tissue, thereby acting as an antiestrogenic agent. This makes choice A the correct answer. Choice B, antimicrobial, is incorrect as tamoxifen does not possess antimicrobial properties and is not used to treat infections. Choice C, androgenic, is incorrect as tamoxifen has antiestrogenic effects, not androgenic effects. Choice D, anti-inflammatory, is incorrect as tamoxifen's main therapeutic action is antiestrogenic rather than anti-inflammatory.

Correct Answer: C

Rationale: The correct answer is C: Electrocardiogram. Amitriptyline can cause cardiac arrhythmias, so an electrocardiogram is necessary before starting treatment. A hearing examination (choice A) is not required before initiating amitriptyline. A glucose tolerance test (choice B) is not indicated for starting this medication. Pulmonary function tests (choice D) are not necessary before initiating amitriptyline for depression.

Correct Answer: A

Rationale: The correct answer is A because respiratory depression is a significant risk when administering morphine, and it can occur within 7 minutes after administration. This information is crucial for the nurse to recognize and respond promptly. Choice B is incorrect because the peak effect of morphine via IV bolus is typically reached within a few minutes, not specifically 10 minutes. Choice C is incorrect because withholding morphine based solely on a respiratory rate less than 16/min may not be appropriate without considering other factors such as pain level, oxygen saturation, and overall respiratory status. Choice D is incorrect because administering morphine over 2 minutes may not prevent respiratory depression if it occurs rapidly after administration. Nurses should be vigilant for signs of respiratory depression regardless of the administration duration.

Correct Answer: A

Rationale: To calculate the rate for the enteral tube feeding, divide the total volume by the total time: 250 mL / 4 hr = 62.5 ≈ 63 mL/hr. Therefore, the nurse should set the pump to deliver 63 mL/hr. Choices B, C, and D are incorrect as they do not match the correct calculation result. B is too low, C is too high, and D is also too high based on the correct calculation.
