Which dessert choice by a client who is prescribed a low-fat diet indicates the client understands the dietary instructions?

Self-determination. Self-determination is the ethical principle that respects the right of a person to make their own decisions. When a nurse respects the decision of a client who refuses a blood transfusion, the nurse is upholding this principle by acknowledging and protecting the client’s autonomy.

Choice A is wrong because beneficence is the ethical principle that involves actively seeking benefits or the promotion of good.

While a blood transfusion may be beneficial for the client, it is not the nurse’s role to impose their own judgment on the client’s choice.

Choice C is wrong because justice is the ethical principle that involves fairness and the just distribution of resources.

A blood transfusion is not a scarce resource that needs to be allocated among competing demands.

Choice D is wrong because fidelity is the ethical principle that involves keeping promises and being faithful to one’s commitments.

A blood transfusion is not a promise or a commitment that the nurse has made to the client.

A 40-year-old client who has a blood pressure of 138/98 mm Hg should be referred for immediate treatment. This is because this client has grade 1 hypertension according to the International Society of Hypertension (ISH) guidelines, which define hypertension as a systolic blood pressure (SBP) of 140 mm Hg or higher and/or a diastolic blood pressure (DBP) of 90 mm Hg or higher in the office or clinic. This client also has a high risk of cardiovascular complications due to their age and elevated DBP.

Choice A is wrong because a 20-year-old client who has a blood pressure of 125/60 mm Hg does not have hypertension. This client has normal blood pressure according to the ISH guidelines, which define normal blood pressure as an SBP of less than 130 mm Hg and a DBP of less than 85 mm Hg in the office or clinic. This client also has a low risk of cardiovascular complications due to their age and low DBP.

Choice C is wrong because a 55-year-old client who has a blood pressure of 142/68 mm Hg does not need immediate treatment. This client has grade 1 hypertension according to the ISH guidelines, but their DBP is normal. The ISH guidelines recommend lifestyle interventions for three to six months before medication in patients with grade 1 hypertension and no comorbidities.

This client may have other risk factors that need to be assessed, such as obesity, diabetes, or smoking, but they do not require urgent referral.

Choice D is wrong because a 70-year-old client who has a blood pressure of 150/78 mm Hg does not need immediate treatment. This client has grade 1 hypertension according to the ISH guidelines, but their DBP is normal. The ISH guidelines recommend a target blood pressure of less than 140/90 mm Hg within three months for patients older than 65 years, and after three months reduce the target to less than 130/80 mm Hg.

This client may have other risk factors that need to be assessed, such as chronic kidney disease, heart failure, or atrial fibrillation, but they do not require urgent referral.
