HESI RN Nursing Leadership and Management Exam 6 - Nurselytic

Correct Answer: A

Rationale: The best method for communicating a vision for the future is to involve others in creating the vision and connect daily work tasks to the vision. This approach fosters ownership and commitment among team members, as they feel part of the vision-building process and understand how their daily tasks contribute to achieving that vision.
Choice B, encouraging staff nurses to openly discuss practice and possible improvements, is important for fostering communication but doesn't directly address creating and communicating a vision.
Choice C, critically analyzing and discussing advances in practice with other nurses, focuses on professional development and knowledge sharing rather than specifically communicating a future vision.
Choice D, actively listening to recommendations, is valuable for gathering input but may not be sufficient on its own for effectively communicating a future vision.

Correct Answer: A

Rationale: The correct answer is A: U waves. A low potassium level (hypokalemia) can manifest as U waves on an ECG. U waves are small, extra deflections seen after the T wave and may indicate cardiac irritability. Absent P waves (
Choice
B) are associated with conditions like atrial fibrillation. Elevated T waves (
Choice
C) can be seen in hyperkalemia, not hypokalemia. Elevated ST segment (
Choice
D) is not typically associated with low potassium levels but can be seen in conditions like myocardial infarction.

Correct Answer: B

Rationale: The correct answer is B: Amiodarone. Amiodarone can affect thyroid function and potentially worsen hypothyroidism, so its use should be carefully considered or questioned in clients with this condition. Levothyroxine (
Choice
A) is the mainstay therapy for hypothyroidism and should not be questioned in this scenario. Calcium supplements (
Choice
C) are not typically contraindicated in clients with hypothyroidism and may be needed if there is a deficiency. Aspirin (
Choice
D) is not directly related to thyroid function and is not a medication that would typically be questioned in a client with hypothyroidism.

Correct Answer: A

Rationale: Administering intravenous fluids is the priority in treating DKA for several reasons. DKA is characterized by severe dehydration and electrolyte imbalances due to hyperglycemia. IV fluids help to correct dehydration, restore electrolyte balance, and decrease blood glucose levels. Administering oral glucose (
Choice
B) would be contraindicated in DKA as the primary issue is high blood glucose levels. Administering a fever-reducing medication (
Choice
C) is not the priority in managing DKA. Administering oxygen therapy (
Choice
D) may be necessary in some cases, but correcting dehydration and electrolyte imbalances take precedence in the management of DKA.

Correct Answer: B

Rationale: When a patient like Albert refuses his bedtime snack, it can lead to hypoglycemia, especially if they are on medication such as insulin. Hypoglycemia can occur earlier than expected due to the lack of carbohydrate intake before bedtime. This situation warrants the healthcare provider to monitor for signs and symptoms of hypoglycemia.
Choice A is incorrect because the given scenario is more indicative of hypoglycemia than metabolic alkalosis.
Choice C is incorrect as NPH insulin peak time is not directly related to skipping a bedtime snack.
Choice D is incorrect as sugar in the urine typically indicates hyperglycemia, not hypoglycemia.
