The nurse from a medical-surgical unit is temporarily assigned to a maternity unit. It would be most appropriate to assign the medical-surgical nurse to a client who had a 1. cesarean delivery 24 hours ago 2. third-degree perineal laceration during delivery 3. premature rupture of membranes (PROM) and is on bed rest 4. vaginal delivery 2 days ago and is scheduled to be discharged

Problem 1 Consider an FM system operating in AWGN. The modulating index of the FM system is

. (the deviation ratio is

). The transmission bandwidth of the system is

, according to Carson's rule. The output SNR of the system at the receiver is

. The following changes are made to the system, all at once The transmitted signal power is doubled. The frequency sensitivity is doubled. Message signal power is kept constant. Message signal bandwidth does not change. Power spectral density of AWGN does not change. Find a) The output SNR of the new system. b) The transmission bandwidth of the new system.

(10 points) Complete the following reactions by supplying the structures of the missing reagents where there is a question mark. Note: some transformations may require more than one step and these steps must be indicated clearly.

QUESTION 2 (COMPULSORY, 20 marks) A rigid uniform slender rod

of length
