A healthcare provider is assessing a client who has heart failure and is taking digoxin. Which of the following findings should the healthcare provider identify as an indication of digoxin toxicity?

Correct Answer: B

Rationale: Yellow-tinged vision is a classic sign of digoxin toxicity due to its effect on the eyes. It can cause a yellow or green visual halo around objects. Bradycardia, constipation, and hypertension are not typical signs of digoxin toxicity. Bradycardia may be a sign of digoxin's therapeutic effect in heart failure, while constipation and hypertension are not commonly associated with digoxin toxicity.

Correct Answer: A

Rationale: The correct answer is A: Quality improvement. Completing an incident report after a client fall aligns with the quality improvement competency of QSEN, as it involves identifying a system issue (fall incident) that needs to be addressed to enhance the quality of care. Choice B, patient safety, focuses more on preventing harm to patients rather than the systematic improvement process. Choice C, evidence-based practice, pertains to integrating research evidence with clinical expertise and patient values in decision-making, which is not directly related to incident reporting. Choice D, informatics, involves using technology and data to support decision-making and improve patient care, which is not the primary focus when completing an incident report.

Correct Answer: D

Rationale: Corrected Rationale: Before administering enoxaparin, it is essential to review potassium levels to monitor for potential imbalances. Enoxaparin, a type of anticoagulant, does not directly affect PT, INR, or platelet count. Monitoring potassium levels is crucial to ensure the safety and effectiveness of the medication. PT and INR are typically used to monitor warfarin therapy, while platelet count is essential for assessing clotting function but is not directly related to enoxaparin administration.

Correct Answer: C

Rationale: The correct answer is C. An elevated serum creatinine level can indicate impaired kidney function, which is crucial to report before administering enalapril. Enalapril, an ACE inhibitor, can affect kidney function, especially in patients with pre-existing renal impairment. Choices A, B, and D are within normal ranges and do not directly impact the initiation of enalapril therapy.

Correct Answer: B

Rationale: During a seizure, it is essential to loosen tight clothing around the client to prevent injury and promote adequate ventilation. Placing any objects, like a tongue depressor, in the client's mouth can lead to airway obstruction or injury. Restraining the client's arms and legs can exacerbate the situation by increasing muscle rigidity and potentially causing injury. Administering oxygen via a non-rebreather mask is not typically indicated during a seizure unless respiratory distress is present.

Correct Answer: B

Rationale: The correct answer is B. Phenytoin can decrease the effectiveness of oral contraceptives, so it is important to inform the client about this interaction. Using an additional form of contraception, such as a backup method, is recommended to ensure adequate protection against pregnancy. Choice A is incorrect because it lacks specificity about the decrease in effectiveness of oral contraceptives caused by phenytoin. Choice C is incorrect as it suggests stopping phenytoin use while using oral contraceptives, which is not the appropriate action. Choice D is incorrect as phenytoin is known to decrease, not increase, the effectiveness of oral contraceptives.

Correct Answer: A

Rationale: The correct answer is A: Creatinine. Gentamicin can cause nephrotoxicity, leading to impaired kidney function. Monitoring creatinine levels helps the nurse detect any potential kidney damage. Choice B, Aspartate aminotransferase (AST), is not typically affected by gentamicin. Choice C, White blood cell count, is not directly related to gentamicin adverse effects. Choice D, Serum glucose, is not specifically monitored for gentamicin adverse effects.

Correct Answer: C

Rationale: In this scenario, with a fetal heart rate (FHR) baseline of 100/min for 15 minutes, the nurse should suspect maternal hypoglycemia. Maternal hypoglycemia can result in fetal bradycardia, which is defined as an FHR less than 110 beats per minute. Maternal hypoglycemia requires prompt intervention to prevent adverse outcomes for both the mother and the fetus. Maternal fever (Choice A) typically presents with tachycardia rather than bradycardia in the fetus. Fetal anemia (Choice B) is more likely to present with other signs such as pallor or tachycardia rather than bradycardia. Chorioamnionitis (Choice D) is characterized by maternal fever, uterine tenderness, and foul-smelling amniotic fluid, but it is not directly linked to the FHR baseline being 100/min.

Correct Answer: A

Rationale: To calculate the correct rate, use the formula: (4 mcg/kg/min * 80 kg) / 800 mcg in 250 mL = 6 mL/hr. This calculation is based on the dose ordered (4 mcg/kg/min) multiplied by the patient's weight in kg (80 kg), divided by the concentration of the drug available (800 mcg in 250 mL) to be infused over 1 hour. Therefore, the correct answer is 6 mL/hr. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided information.
