ATI Pharmacology Proctored Exam

Correct Answer: A

Rationale: The correct instruction for a client prescribed Digoxin for heart failure is to contact the provider if the heart rate is less than 60/min. Digoxin can affect heart rate, and a heart rate below 60/min may indicate toxicity, requiring prompt medical attention. Checking the pulse rate accurately and seeking medical advice are essential components of safe medication management. Choices B, C, and D are incorrect. Choice B is related to checking the pulse rate but does not address the critical action of contacting the provider if it is below 60/min. Increasing intake of sodium (Choice C) is inappropriate as high sodium levels can worsen heart failure. Taking Digoxin with food if nausea occurs (Choice D) does not address a critical aspect of Digoxin administration related to heart rate monitoring.

Correct Answer: A

Rationale: Corrected Rationale: Hydrochlorothiazide, a diuretic, can lead to electrolyte imbalances, particularly hyponatremia (low sodium levels). The nurse should closely monitor the client's sodium levels due to the potential adverse effect of Hydrochlorothiazide. Incorrect Rationales: - Hyperkalemia (Choice B) is less likely to be caused by Hydrochlorothiazide; in fact, it can lead to hypokalemia. - Hypercalcemia (Choice C) is not a common adverse effect of Hydrochlorothiazide. - Hypoglycemia (Choice D) is not directly associated with Hydrochlorothiazide use.

Correct Answer: D

Rationale: Hydrochlorothiazide is a diuretic that can lead to dehydration due to increased urination. Signs of dehydration include dry mouth, increased thirst, and decreased urine output. It is essential to educate the client to monitor these signs and seek medical attention if they occur. Choice A is incorrect because Hydrochlorothiazide is usually taken in the morning to prevent disruption of sleep due to increased urination during the night. Choice B is incorrect because while Hydrochlorothiazide can lead to potassium loss, consuming foods rich in potassium is not a specific instruction related to this medication. Choice C is incorrect because taking Hydrochlorothiazide with a meal is not a specific requirement for its administration.

Correct Answer: C

Rationale: Neutropenia is a serious adverse effect associated with ACE inhibitors like Captopril. Neutropenia refers to a decreased level of neutrophils, which are important white blood cells in fighting infection. Monitoring the client's complete blood count (CBC) is essential to detect neutropenia early. Hypokalemia (Choice A) is more commonly associated with diuretics, not ACE inhibitors. Hypernatremia (Choice B) is an increase in sodium levels, not typically caused by Captopril. Bradycardia (Choice D) is not a common adverse effect of ACE inhibitors like Captopril.

Correct Answer: A

Rationale: Tamoxifen is contraindicated in clients with a history of thromboembolic events, such as deep-vein thrombosis, due to the increased risk of blood clots forming and leading to serious complications like pulmonary embolism. Clients with a history of deep-vein thrombosis are at a higher risk of recurrent thromboembolic events when taking tamoxifen, making it unsafe for such individuals. Choices B, C, and D are not contraindications for tamoxifen therapy, as migraine headaches, hypertension, and anemia do not directly interact with tamoxifen's mechanism of action or pose significant risks when used together.
