For which of the following behaviors would limit setting be most essential? The client:

displays hypervigilance and refuses to attend unit activities.

is flirtatious toward staff members of the opposite sex.

urges a suspicious client to hit anyone who stares at him.

clings to the nurse and asks for advice about inconsequential matters.

Answer and Explanation

The Correct Answer is C

Choice A Reason
Limit setting may be helpful for a client who displays hypervigilance and refuses to attend unit activities, as it can provide clear expectations and help reduce anxiety. However, this behavior does not pose an immediate risk to the safety of others, making limit setting less essential compared to behaviors that could lead to harm.

Choice B Reason
While being flirtatious toward staff members may be inappropriate and require intervention, it is typically addressed through professional boundaries rather than limit setting. Limit setting in this context would involve clarifying acceptable behaviors within the therapeutic relationship.

Choice C Reason
Urging another client to commit violence is a behavior that necessitates immediate limit setting. This behavior poses a direct threat to the safety of others and disrupts the therapeutic environment. Limit setting here would involve immediate intervention to prevent harm and to maintain a safe environment for all clients.

Choice D Reason
A client who clings to the nurse and seeks advice on inconsequential matters may benefit from limit setting to encourage independence and appropriate use of staff time. However, this behavior is not as disruptive or dangerous as inciting violence, making it a lower priority for limit setting.

Correct Answer is A

Explanation

Choice a reason:
Bleeding at the arterial puncture site is a primary concern post-cardiac angiogram, as it can lead to significant blood loss and hematoma formation. The nurse must frequently monitor the site for any signs of bleeding or hematoma, apply pressure if necessary, and report any abnormalities to the physician immediately.

Choice b reason:
Cardiac dysrhythmias may occur due to irritation of the heart muscle by the catheter during insertion. Monitoring the client's heart rhythm is essential to detect any new onset of arrhythmias, which could indicate complications from the procedure.

Choice c reason:
Electrolyte imbalances can result from the contrast dye used during a cardiac angiogram. The dye can affect kidney function, leading to changes in electrolyte levels. Monitoring electrolyte levels is important to prevent complications such as arrhythmias or fluid imbalances.

Choice d reason:
While discomfort at the catheter insertion site is expected, it is typically mild. However, the nurse should assess for discomfort as it may indicate other issues such as infection, bleeding, or a reaction to the procedure.

A. Ceftriaxone, with a white blood cell count of 16,000 u/L. B. Zafirlukast, with an AST of 30 units/L and ALT of 20 units/L. C. Theophylline, with a theophylline level of 21 mg/dL. D. Prednisone, with a glucose level of 110 mg/dL.

Correct Answer is C

Explanation

Choice A Reason
Ceftriaxone is an antibiotic that may be prescribed during COPD exacerbations to treat or prevent infection. A white blood cell count of 16,000 u/L indicates an elevated level, which could be a response to infection. Therefore, ceftriaxone would be appropriate, and there is no need to question this medication based on the white blood cell count.

Choice B Reason
Zafirlukast is a leukotriene receptor antagonist used for the prophylactic treatment of asthma, and it may be used off-label for COPD. AST and ALT levels are liver enzymes, and the values provided (AST of 30 units/L and ALT of 20 units/L) are within normal ranges. Thus, there is no immediate concern regarding liver function that would prompt the nurse to question the use of zafirlukast.

Choice C Reason
Theophylline is a bronchodilator used in the treatment of COPD. However, a theophylline level of 21 mg/dL is above the therapeutic range, which is generally considered to be 5-15 mg/dL. Levels above 20 mg/dL are associated with toxicity and can lead to serious side effects such as seizures or arrhythmias. Therefore, the nurse should question this medication due to the high theophylline level.

Choice D Reason
Prednisone is a corticosteroid that may be used to reduce inflammation during COPD exacerbations. A glucose level of 110 mg/dL is slightly elevated but may be expected as corticosteroids can increase blood sugar levels. This would not typically be a reason to question the use of prednisone unless the patient has poorly controlled diabetes or other specific contraindications.
