A nurse is reviewing the laboratory results of a female client who has hypovolemia. Which of the following laboratory results would be a priority for the nurse to report to the provider?

Correct Answer: B

Rationale: The correct answer is B: Potassium 5.8 mEq/L. In hypovolemia, there is a decrease in blood volume leading to electrolyte imbalances. Potassium levels outside the normal range can be life-threatening, causing cardiac arrhythmias. Therefore, a potassium level of 5.8 mEq/L is a priority to report to the provider for prompt intervention. Rationale for why the other choices are incorrect: A: BUN within the normal range. It may indicate dehydration but not immediately life-threatening. C: Creatinine slightly elevated, indicating kidney function impairment but not as critical as potassium imbalance. D: Sodium within acceptable range, not an immediate concern in hypovolemia.

Correct Answer: C

Rationale: The correct answer is C because metformin is typically held before a coronary angiogram due to the risk of lactic acidosis. This information is crucial for the health care provider to know to prevent potential complications during the procedure. Option A is not as urgent as the patient's current medication status. Option B is less relevant as it does not impact the procedure directly. Option D is important but not as critical as knowing the status of metformin intake. Reporting the patient's current medication, especially metformin, is vital for ensuring patient safety during the coronary angiogram.

Correct Answer: B

Rationale: In DKA 6 hours into treatment, blood glucose 80 mg/dL demands immediate intervention, not ketones, ABGs, or urine output. DKA starts with hyperglycemia; dropping to 80 risks hypoglycemia insulin needs adjustment, fluids may shift to dextrose. Ketones linger, ABGs show mild acidosis (expected), and high output reflects rehydration. Leadership acts here imagine confusion setting in; swift glucose correction prevents seizures. This reflects nursing's vigilance in metabolic crises, ensuring safe DKA resolution effectively.

Correct Answer: C

Rationale: The correct answer is C: Using barcoding technology for medication administration. This strategy is most effective for reducing medication errors because it helps ensure the right medication is given to the right patient at the right time. Barcoding technology allows nurses to scan both the patient's wristband and the medication label to verify accuracy before administration, reducing the risk of errors due to human factors. A: Increasing the nurse-to-patient ratio may help with workload distribution but does not directly address medication errors. B: Providing ongoing education is important but may not be as effective as implementing technological solutions like barcoding. D: Increasing the use of PRN medications may actually increase the risk of errors if not managed properly. In summary, using barcoding technology for medication administration is the most effective strategy as it directly addresses the root cause of medication errors by ensuring accurate medication administration.

Correct Answer: B

Rationale: The correct answer is B: Limit the client's time with visitors to no more than 30 minutes per day. This is the correct precaution because shigella is transmitted through fecal-oral route. By limiting the client's time with visitors, the risk of spreading the infection to others is minimized. Explanation for why other choices are incorrect: A: Having the client wear a mask when receiving visitors is not necessary for preventing the spread of shigella, as it is not transmitted through the air. C: Assigning the client to a room with negative-pressure airflow exchange is more suitable for airborne infections, not for shigella which is transmitted through fecal-oral route. D: While wearing a gown when caring for the client is a good infection control practice, it is not specifically indicated for preventing the spread of shigella through contact with visitors.

Correct Answer: B

Rationale: Heart failure impairs cardiac output, causing fluid retention a key monitoring focus. A weight gain of 1 kg (2.2 lb) in 24 hours signals rapid fluid accumulation roughly 1 L indicating worsening failure or decompensation, requiring provider notification for diuretic adjustment or evaluation. Bounding pulses suggest hyperdynamic states, not typical failure, while dependent edema and fatigue, though common, are expected chronic signs, less urgent unless acute. Rapid weight gain is a red flag per heart failure guidelines, demanding prompt reporting to prevent pulmonary edema or hospitalization, reflecting the nurse's role in early detection and intervention to stabilize the client's fragile condition.

Correct Answer: C

Rationale: Situational theory, as Ms. Caputo learns, adapts style to context; Laissez-faire suits mature, expert followers by granting autonomy. Democratic involves participation, Authoritarian demands control, and Bureaucratic enforces rules less fitting for self-directed nurses. In a skilled unit, a Laissez-faire leader might trust RNs to manage patient loads independently, enhancing efficiency. Ms. Caputo could adopt this with seasoned staff, ensuring flexibility aligns with their expertise, a practical approach to elevate care quality in her new role.

Correct Answer: A

Rationale: The correct answer is A: Certification to contract. Certification to contract refers to having the legal capacity and authority to enter into a contract with an employer. This means the individual meets the necessary requirements and is legally allowed to engage in contractual agreements. Rationale: 1. Certification implies that the individual has met specific qualifications or criteria, ensuring they have the necessary skills and knowledge to engage in contract negotiations. 2. To contract indicates the ability to enter into a legally binding agreement, which is essential when establishing an employer-employee relationship. 3. The term "certification to contract" specifically addresses the ability to form contracts, distinguishing it from the other choices which do not directly relate to contractual agreements. Summary of Incorrect Choices: B: Certification to represent - While representation may be involved in contract negotiations, this choice does not directly address the ability to enter into a contract with an employer. C: Bargaining agreement - This refers to an agreement between labor and management, not the individual's ability to enter into

Correct Answer: B

Rationale: Before ceftriaxone, review serum creatinine, not WBC, glucose, or potassium. Cephalosporins need renal adjustment creatinine flags function, guiding dosing. Others track infection or unrelated. Leadership checks this imagine oliguria; it prevents toxicity, aligning with antibiotic care effectively.
